ANY MODERN ASTRONOMY program will work for this lesson. I recommend using the freeware Astrolog 5.41G with the freeware JPL-DE406 Swiss Ephemeris, Carte du Ciel 2.75 which is also freeware, and includes links to download dozens of freeware catalogues and other plugin options, or check out the SkyMap 9 demo version on my links URL: http://groups.google.com/groups?selm...amesh-frog.org This is very basic, and will show you how every planet visible to the naked eye, which includes the Sun, Moon, Mercury, Venus, Earth, Mars, Jupiter, Saturn, & Uranus, this will show you how these planets move as seen from the Earth in conspicuously repetitious and predictable patterns which are easily counted by days, months, and years between repeating sidereal and synodic multiples. This absolutely destroys any and all arguments against the ancients being perfectly able to see the motion of the planets against the night sky and counting by days, months and years to predict sidereal & synodic periods for each planet at least out to Saturn and possibly to Uranus, since it rarely can be seen with the naked eye. This is a big deal because secular academia has closed their eyes to timeless science and its reproducibility. This clearly transcends simple astronomy, but includes astrology, metaphysics, and all spiritual implications. Limit your program to what is visible to the naked eye. No guesswork & no speculation. Your astronomy software reliably emulates what we'd see when viewing the night sky in that direction, at that time from that location, conveniently, efficiently and with impressive accuracy. Of course, the view is better through a good telescope, or through the unaided, human eye, since it is assumed that ancients didn't have other means to see the stars. That's a humongous ad hoc assumption, but I'm granting modern-day atheistic science that much and I still win. Accurate positions of planets and stars is all we need for this lesson. Your favorite software will work fine. No telescope needed. We can see this all with our eyes, so reduce your software's star magnitude limit to five, and assume Uranus, Neptune and Pluto to be nonexistent (not as Gods, but to pacify the unbelieving scientist). For this lesson, we're concerned only with heliacal ri- sings of each planet separately, which depends only on sufficient angle between the planet and the Sun, so it can be spotted against background stars before sunrise. The Sun must be about 18 degrees below the horizon for full darkness and a little less for heliacal phenomena. This angle varies with each planet, and each star, and time of year, temperature, pressure, how good your eye- sight is, the geographical latitude of observation and local horizon, obstructions and circumstances of light pollution, smog, haze from forest fires, volcanos, etc. While these conditions can vary to extremes, generally, provided reasonably good seeing conditions towards the eastern horizon about an hour or so before sunrise, as you look to the east (from moderate latitudes) you can barely make out a planet that you expect to see rising heliacally on or about that date. If you miss it, then try again in a couple of days and you're bound to spot the planet you're looking for if it's Mars, Jupiter or Saturn; or plan ahead and begin looking sooner if it's Mercury whose orbit you can see is eccentric. You know that each planet has predictable orbital patterns, and although these patterns vary over the short-term, over the long-term they become more and more predictable to fractions of a degree in sidereal longitude & latitude. That's how you know that Venus is the most predictable, since Venus has the least eccentric orbit. We see this behavior of Venus through heliacal risings or settings, especially at maximum elongations inferior or superior. If getting up at four in the morning is not your style, simply open your astronomy program and set it for your geographical location and voilla! You're ready to view to heliacal risings of every planet--against the stars. In the next part we focus on Saturn's heliacal risings. Open your favorite astronomy program. As always, I use Astrolog, so all examples given refer to JPL ephemeris DE-406 with Abramov's expanded version of fixstars.ast provided by S. Moshier using the Astronomical Almanach. All data is accurate to within several milliarcseconds, which is vastly better accuracy than the plus or minus half a degree or thirty arcminutes we can achieve with an extended pinky finger at arm's length measuring one arcdegree...twice the apparent diameter of a full Moon. Three closed middle fingers spans five degrees, or the whole hand equals about ten degrees. You can calibrate simple hand measurements by memorizing bright "marking" stars near the ecliptic by their approximate longitude on the caelestial zodiac. The constellations and their associated myths help us to easily locate and identify stars as we become familiar with their appearances and their order in the sky. This is where Carte du Ciel or SkyMap comes in handy, since they depict the stars and planets graphically, and include millions more objects and dozens of unabridged catalogues for the astronomer. However, only Astrolog can chart the marking stars and planets by their zodiacal, constellational coordinates as used by ancient stargazers for tracking the planets. The complete list of almost 1000 stars is posted on my website, but here's an abbreviated list for convenient reference with the values rounded off to whole degrees and favoring brighter stars in the northern hemisphere. Remember the goal is not to memorize every star but is to estimate a planet's position at its heliacal rising, setting, opposition and other repeating synodic phases against the fixed background of this caelestial sphe Name Longit.

Set the date & time to December 31, 2003 12 AM, and you'll see Saturn at opposition in 15 Gemini. This is just one "pinky finger" in longitude from Alhena at 14 Gemini. With the Sun in 15 Sagittarius, then Saturn will be at southing about midnight LAT January 1, 2004. - From this we can estimate Saturn's next opposition, by adding 378 days, which is January 13, 2005. But Saturn is a little slow in getting there, reaching opposition the next day January 14, in 29 Gemini. The oppositions, which we'll skip for Jupiter and Mars, prove to us the planets Mars, Jupiter and Saturn, are orbiting the Sun beyond Earth's orbit, and these orbits are predictable, especially over long-term observations. As with Saturn, by adding 3781 days to its synodic phase, we arrive at Saturn's tenth opposition counting from January 1 2004, which is May 9, 2014, again missing exactitude by only one or two days, due to Saturn's moderate eccentricity and about 2.5 degrees inclination to the ecliptic. For long-term predictions, the ancient Babylonians noticed that 9 sidereal orbits of Saturn coincided with around 256 synodic periods and 265 tropical years speaking in round numbers. Add 265 years to January 1, 2004 and we have January 1, 2269. Sure enough, there's Saturn near opposition in 14 Gemini directly above Alhena and just two days from true opposition January 3, 2269, showing that the Babylonians knew what they were talking about two thousand years before Christ. It's no mystery, but is readily observable, predictable and reproducible in the laboratory of the night sky, like heliacal risings. The predawn risings of stars and planets have been the carefully watched and predicted since men could mark a cave wall with a piece of coal, blood or whatever else has handy. Primitive stone observatories emerged which had much greater longevity, and showed the teamwork of prehistoric stargazers, and the importance they placed on the ephemeris of the Sun, Moon & Stars to the Earth. Naturally, the Sun is the single most important object visible in the Earth's sky. Man has watched the Sun as it rises and sets every day since humankind has walked the Earth. All life forms follow the diurnal circadian rhythm of Earth's daily rotation in one way or another. Hence the Sun formed the fundamental basis of tracking time from the beginning of every civilization that has come and gone, from primitive tribes of early hominids to more advanced human cultures, most of which are too distant in the past for their records to have survived. More recently, the Egyptians, Babylonians, Mayans, and others around the post-deluvian world are close enough in time for many of their records to be extant, mostly bits and pieces, some fairly intact, like the pyramids. In mans present time, secular-religious archaeologists prefer to believe that civilization is basically under 7000 years old worldwide, due to their historical ties to the Roman church, and continued use of the language in their laws and their sciences. This is not to blame the ancient translation of the bible, the Vulgate, but has been the politics of religion, as men serve mammon. After all the bible predicted this would happen, so it isn't surprising that the schism of religious-apostasy should continue to rule the minds of men. Yet the Moon & Stars have continued to illuminate the night sky for geological aeons and shall continue to do so for aeons. So it is that Saturn has been rising and setting helia- cally in very predictable intervals and shall continue to do so for many long ages to come. Since the initial date and time for observation of Saturn before sunrise will vary, we know the Sun needs to be some 18 degrees below the horizon to ensure visibility of any brighter star or planet from moderate latitude any time of year, weather permitting. But in fixed locations, i.e. where ancient and antediluvian population centers flourished, the heliacal risings of stars and planets were readily estimated to within a few days time and by the seasons of the year, tied directly to planting, harvesting and every single aspect of their lives. Thus astrology was the natural result of watching and predicting when the stars and planets would rise and set, by knowing where the planets are day and night. This knowledge was made by simple observation, counting days, months and years between cycles and phases. When Saturn rose heliacally, it was always about 378 days give or take a day or two since the last time it was observed to rise heliacally. With each consecutive heliacal rising of Saturn, fixed stars in the background showed that Saturn moves about 13 degrees in keeping with the Sun's progress relative to the stars some 13 days later each year--again, give or take a day or two, talking about long-term averages rounded off to integer days since the whole premise is to show that ancient stargazers could and did see that the planets clearly orbit the Sun, and that they could readily observe and recognize the sidereal and synodic orbits by watching the heliacal risings of planets and stars. The accuracy of the ancient ephemeris increased commensurate with continued calibration by observation of heliacal phenomena over the centuries and millennia of that civilization from its rise until its fall. The quality of long-lost very ancient ephemeredes is known by mans inherent ability as a man to see the night sky and to notice patterns and repetition in nature. These are perfectly natural talents that all people are born with--at least most people are. Once again, this comes down to how much credit we give prehistoric man. There are anthropologists who have recognized that early man was smarter than modern day, secular-religious science had theretofore acknowledged. Likewise the recognition that at least semi-intelligent hominids have been here many millions of years earlier than the orthodoxy used to believe albeit some still cling to their hopelessly obsolete superstitions about the antiquity of man, etc, it is clear that man and man-like sentient beings have roamed the Earth for aeons. One might reasonably argue that dolphins or whales are smart enough to notice the planets and stars rising and setting, and to count the days and years of these events. Elephants are known to remember things very well. At a minimum, we can safely say that early man was intelligent enough to count the days, months or years of observable heliacal phenomena and we see that such observable events are predictable, simply counting these events by days, months and years. __________________________________________________ ____ I think this is what makes modern astronomers angry at those of us who have realized that planetary motion is not nearly as mysterious as they'd like you to believe. __________________________________________________ ____ The Egyptians, Babylonians and Mayans showed admirable levels of sophistication in their astronomical records and their ability to predict very long-term periodical events, the great year of precession being among these, since the Earth's axis of rotation visibly gyrates one degree against the fixed stars about every 26000 solar days, which is about 71 tropical years, two months and nine days, therearound. This is according to the Mayan astronomers, whose astronomical skills were comparable to those of the Babylonians. Both left records proving that they could see the night sky, and that they could accurately count and predict periodic planetary orbits against the starry background of the caelestial sphere. As in this case, we *see* Saturn observably progresses about twelve degrees every year against the stars seen from Earth. Every twenty-nine and a half years, Saturn goes full circle against the stars, and over centuries of observation we see that Saturn circles the Sun nine times every two hundred sixty-five years--meaning that Saturn advances closer to twelve and a quarter degrees longitude per year thereby making short-term estimates of Saturn's motion a little more accurate and reliable than our round number of twelve degrees per year. Thus we may safely predict that Saturn will have moved east by closer to forty-nine degrees every four years, plus our ephemeris for Saturn has improved significantly by repeated observation and simple mathematical deduction. We'll notice Saturn's thirteen degree advance at times of entering or leaving retrograde motion and that this retrograde lasts for about one hundred thirty-eight or so days centered on inferior conjunction or opposition to the Sun. Every three hundred seventy-eight days, we see these motions repeat, when Saturn appears to stand still in the sky then begin to move backwards for some four and a half months before standing still again and returning to normal motion. Every time we see it again, about 378 days have passed and Saturn is approximately 13 sidereal degrees from where it was last time around. Carte du Ciel is especially useful for animating these apparent synodic motions against the background of the stars, since you can fine-tune increments down to days, hours and minutes, and mark the locations with "finder circles" to readily observe a planet's motion relative to the stars & constellation figures, and to the other planets. Although the accuracy of the ephemeris is not very reliable beyond plus or minus four thousand years, especially for the Moon, you can view distant dates to circa 20,000 years BC / AD. While tropical seasons can be way off the mark the apparent motion of a planet to the stars may not be far off the mark for say, 9000 BC. You just won't know the season, or the Moon's position at such a distant date, but other planets are probably within a couple of degrees of where they actually were. Not that this matters much, since you are simply using the present-day ephemeris to view synodic and sidereal motion of the planets that are visible and predictable. For example, most of us'll probably be up and about at midnight January 1, 2004. If your skies are clear, you should remember to walk outside for a moment and check out Saturn in 15 Gemini--just above and east of Alhena, and right below Mebsuta which marks sidereal 15 Gemini just 2 degrees above the ecliptic. Your extended thumb at arm's length spans about two arcdegrees thus you'll see that Saturn is maybe a pinky fingernail's width or so (about 2/3's of a degree) below the ecliptic at the time of observation. Since Asellus Australis (see list above) marks 14 Cancer right on the ecliptic (actually +0:04'38" but round degrees are all a stargazer needs), and bright Regulus at 5 Leo is less than half a degree above the ecliptic, you can quickly visualize the line, rather the arc of the ecliptic across the sky. Jupiter at 24 Leo and about a degree above the ecliptic should be visible in the eastern sky. Sirius at 19 Gem and 40 degrees below the ecliptic will be hard to miss in the southern sky (unless you live north of Barrow, Alaska). If you live in the southern US or similar latitude you might spot bright Canopus at 20 Gem -76 degrees barely above the south horizon. Orion should be in clear view below right of Saturn. See if you can spot Al-debaranu, the prime fiducial of the caelestial zodiac at 15Tau00 and 5 degrees below the ecliptic. As you see, when you look at a planet in the night sky the background stars help you to locate the planet's longitude and latitude, hence confirming previous predictions, and calibrating future predictions. In ancient times this was done for centuries & millennia. Let's look at Saturn heliacally. Just to be on the safe side, we'll put 30 degrees past Saturn for the predawn Sun. That ought to make it easy to spot Saturn before sunrise, whether you're watching from the old, royal Greenwich observatory at 25 meters above sea level & 00E00:00 longitude 51N28:38 latitude, or viewing atop the Great Pyramid at 31E09:00 29N58:51, or from the Sun Pyramid in Teotihuacan, Mexico ~19:44N 98:50W or from the site of ancient Babylon 44E24 32N33. Use your own default observation location, set up your favorite astronomy program to watch the sky from there. I'm using my own location here in central Colorado USA. Saturn is plainly visible at heliacal rising August 14, 2004 after about 3:30 AM MST. For continuity, I've set Astrolog to 12 PM August 14 2004 or Julian Day 2453232, with Saturn 27 Gemini and the Sun 27 Cancer. We'll add the 378 days for Saturn's synodic period, to August 27, 2005, with Saturn 10 Can and Sun 9 Leo. Like before we are just a day short, so on August 28, 2005, Saturn is rising about 3:50 AM, and it is apparent that Saturn's some 13 degrees further along in the caelestial zodiac than it was back on August 14 2004. Add twice 378 days, which is 756 days, and we have September 9, 2006 which is about two days shy of Saturn 30 sidereal degrees to the Sun, thus September 11 2006 finds Saturn rising at 4 AM. Let's jump ten times 378, which we know from our previous observations is closer to 3781 than 3780. The date is December 21, 2014. Low and behold, Saturn's at 5 Scorpio and the Sun is 5 Sagittarius, right where we expected it to be. Remember, Saturn was at 27 Gem back on August 14, 2004 with the Sun 27 Can. Now, ten times Saturn is heliacally risen we see that Saturn is 5 Sco and the Sun 5 Sag. That's near 128 degrees that Saturn has progressed in ten synodic periods or ten times our round figure of 13 degrees. Again, as observations are made over longer and longer periods of time, ephemeris calibration and improvements are the inevitable result. By the way, Saturn rises near 6 AM on December 21 2014. These long-term observations of the heliacal phenomena inevitably reveal the limits as to how far the planets can appear to stray from Earth's ecliptic with the Sun, revealing each planet's orbital inclination to Earth's, and also revealing other obvious limits, such as Venus and Mercury display their orbital eccentricity when at maximum elongation, Venus very little, Mercury a whole lot more. This plainly shows the observer that Venus & Mercury are closer in heliocentric orbit than Earth is, and of course the paths of Mars, Jupiter & Saturn show that they are further away from the Sun in their helio- centric orbits than Earth is. We'll cover more on this in later parts. Jupiter is next on the list of planets. Julian Day 2453309, 12 UT October 30, 2004. Jupiter is at 13 Virgo, 30 sidereal degrees from the Sun 13 Libra. Jupiter rises about 4:50 AM (here in central Colorado) just below bright Venus at 7 Virgo. Zaniah (etaVir) is between them near 10 Virgo. Remember, we are measuring the sky with our naked eye and extended hand, so round degrees, maybe down to a sixth of a degree, or ten arc- minutes, is as good of accuracy as we can achieve. You can see that the modern accuracy of JPL's ephemeris is based on observations made by large observatories, and formulated using advanced knowledge of mathematics and physics. E.g. here's a chart for Sat 30-Oct-2004 12 UT. These values are rounded off to the nearest arcseconds of longitude and latitude, while the internal accuracy of the software is good to milliarcseconds (JPL-DE406): Aldebaran : 15Tau00'00" -5:28'00" Venus : 6Vir55'17" +1:32'47" Zaniah : 9Vir30'15" +2:35'21" Jupiter : 12Vir35'49" +1:07'05" Sun : 12Lib32'48" +0:00'00" Ancient observers would commonly use a measuring stick or metal rod notched with linear increments calibrated by the observer which he or she could comfortably hold at arm's length between both hands, ensuring a uniform perspective of sidereal measurement. But we will limit our ancient observers as having nothing but themselves to view the heavens, since that's all that they needed to clearly view the predictable motions of the planets against the fixed background of stars. Easily accurate to plus or minus one degree, simple enough so children could be taught to do this and carry on the stargazing tradition, counting the days, weeks, months, and years, planting, harvesting, worshipping by the ephemeris and its religiously-observed calendar--the religion of the stars. As each civilization developed, and became more sophisticated, they organized and specialized, so that astronomical observation, astronomy, and their logical deductions based on astronomical observations--meaning mathematics--ergo astrology, became the disciplines of specialists so that others in their community could go about their business. In ancient times, the astrologer was synonymous with the mathematician, "star-logician" in the most literal sense. Even in our day and age, it was only within the last few centuries that astrologer and astronomer reached a schism, since astrologers had long-since ignored the proper mathematics of astrology, and astronomers became disenchanted with the illusions yet perpetuated by today's tropicillogical astrologers and other schisms of astrology,--all who've hopelessly lost their grasp on the ancient practice of star-logic. Since this schism, astronomers have changed their ways of measuring the sky such that "constellations" became synonymous with unequal boundaries associated with the asterisms or some 88 familiar groups of brighter stars instead of the ancient method which divides the entire caelestial sphere into twelve equal meridians as signs with meridians of latitude from the caelestial equator. Modern astronomers began referencing positions only to Earth's terrestrial equator by its intersection on her ecliptic. Next time there's a "pole shift", or crustal displacement (or both?), that'll screw up their method of measuring the sky in a heartbeat. Meanwhile Earth's slow gyration of precession continues to change modern astronomer's coordinates. For example, look at Regulus at 5 Leo near the ecliptic. In 8000 BC, Regulus was at 5 Leo. In 8000 AD, Regulus will still be at 5 Leo. The position of Regulus is easy to see and easily recalled. Only the slight, very long-term wobble of the ecliptic itself affects how we chart latitude of stars near the ecliptic, and also the longitude of stars farther away from the ecliptic. As a result, Regulus might be close to a degree from the ecliptic at some remote epoch but it's still going to mark 5 Leo for a long time to come, irrespective of precession, pole-shift or annihilation of civilization. Any survivors can point up at Regulus and confidently say "Look! There's Regulus 5 Leo", and any planet passing nearby will certainly be identified by its position--relative to a recognizable fixed star, and certainly not by its "RA/Dec". As for this example, on Julian Day -1200514, 1-Jan--7999 (8000 BC Gregorian) Carte du Ciel shows Regulus at 0h46m35s +4*36'06", and Carte du Ciel shows Regulus at 15h29m45s -17*53'29" on Julian Day 4643000 1-Jan-8000 (8000 AD). For a caveman marking scores on a cave wall to remember positions of planets relative to nearby stars counting days, months and years between repeating heliacal risings and other predictable synodic phases relative to the Sun, anyone can see that the positions of planets are most readily and easily tracked by their positions to visible stars, and that those stars remain fixed in their position on Earth's caelestial sphere with subtle proper motion so slow that it takes millennia even to be noticed by the best of naked-eye astronomers. Hence Orion's Belt, for example, is very close to the same position in the sky as it was when they built the Great Pyramids 10,500 BC, since the three stars of the belt have very low proper motion. So Mintaka 28 Tau, Alnilam 29 Tau, and Alnitak the "Great Pyramid" star at 0 Gem have illuminated the same positions on Earth's caelestial zodiac ever since. So when we say Jupiter is in 13 Virgo October 30, 2004, we can easily see where it is in relation to the stars before sunrise, since the stars tell us where 13 Virgo is. In this case, Zaniah at 10 Vir is nearby, so it is easy to estimate Jupiter's position to plus or minus a degree of certainty. With this simple observation, the next heliacal rising of Jupiter is easily predicted by adding 400 days to October 30, 2004, since 400 days is the average period that Jupiter has been seen for ages to repeat its synodic cycles. That is December 4, 2005, but Jupiter is about five days past the 30-degree mark from the Sun. November 29, 2005 finds Jupiter 12 Libra and the Sun in 12 Sco, and Jupiter will be rising near 5:30 AM from my location. With Spica and Arcturus over rising Jupiter, you can be sure where 29 Virgo is. But Kappa Virgo at 10 Lib and +3 latitude--although it's a lot closer to Jupiter--may be difficult to see at 4.18 magnitude. The star called "109 Vir" is a bit brighter at 3.72 magnitude and marks 13 Libra near +17 latitude. The important thing is to know which stars that you're looking at, and their approximate longitude & latitude in the zodiac. In the 395 days between heliacal rising, Jupiter has moved some 29 degrees. From this we expect Jupiter will complete one sidereal orbit approximately every 12 years. Jump ahead 4000 days from October 30th 2004, and we arrive at October 13 2015--eight days too late. We must go back to October 5, 2015, with Jupiter 17 Leo and the Sun 17 Virgo. From this we find Jupiter has moved from 13 Vir to 17 Leo, 26 degrees before the completion of one sidereal year for Jupiter. Estimates from our observations in 2004 & 2005 led us to believe that Jupiter would take about 12 years to complete one sidereal orbit. Jupiter's tenth heliacal rising showed us that Jupiter moved about 334 degrees over 3992 days. We might extrapolate off this, and figure that Jupiter will make about 360 degrees in another 311 days making a rough estimate 3992 + 311 = 4303 days for a sidereal year of Jupiter based on a total of three observations. Let's look at the next rising of Jupiter 400 days from October 5, 2015, November 8 2016. Now we're about four days late, so go back to November 4, 2016, for Jupiter 17 Virgo and the Sun 17 Libra, rising about 4:50 AM at my location. So for eleven heliacal risings 30 degrees from the Sun, it took 4388 days, and Jupiter transited through the zodiac from 13 Vir October 30, 2004, to 17 Virgo on November 4 2016. That's fully 360 degrees and 4 extra degrees that Jupiter was observed to move over the course of 4388 days and a touch more than 12 years. Simple interpolation estimates a sidereal year at 4340 days, 37 days higher than our previous estimate but is now based on four observations not just three. Further observations empirically calibrate our rough estimates. - From simple observation we were able to deduce Jupiter takes a little less than 12 years to complete one side- real orbit, since we are plus 4 degrees after 12 years. Repeated observation refined our estimate to 4340 days. After centuries, the ancients were able to winnow this down to some 4332 days or about 11 tropical years plus around 316 days that it takes Jupiter to orbit the Sun. It doesn't take any "rocket scientist" but only common sense with a little simple addition and subtraction of round degrees, days and years. The stargazer could see Jupiter go retrograde for some 121 days centered on in- ferior conjunction (opposition), and see these synodic events repeat every 400 days by the long-term averages. Ancient Babylonian astronomers were sufficiently adept to notice that 36 sidereal orbits of Jupiter was quite close to 427 tropical years and 391 synodic periods of Jupiter. Just add 427 years to October 30, 2004 to see if they knew what they were talking about. Try October 30, 2431. Just 6 days later Jupiter is 30 degrees from the Sun with Jupiter 12 Vir and the Sun 12 Vir. That's just one degree from where they were back in 2004. The ancient synodic multiple for Jupiter is right in there. Next we'll look at Mars, which has the longest synodic period of all the planets. We can see that Mars is the first planet beyond Earth's orbit since Mars is moving much faster through the caelestial zodiac than Jupiter or Saturn. But like the Jovian planets we can see that the elongations of Mars from the Sun reach oppositions on an observably predictable periodic basis as is true for heliacal risings, settings, squares, trines or any repeating angle of aspect to the Sun. Heliacal risings are being treated as semisextile aspect for continuity, and the nice round number thirty degrees is convenient, easy to remember and to measure by hand, since a whole hand or fist plus three closed middle fingers at arm's length together makes 15 degrees, two whole fists make about 20 degrees, depending on your physical type. The angle from outstretched thumbtip to pinky fingertip is some 25 degrees, but you must calibrate your own hands and fingers to estimate a perspective angle accurately. An easy way to do this is to stand in a rectangular or square room and see how many hands, fists, and fingers it takes to measure 90 degrees, i.e. from wall to wall. Six times a fist plus 3 closed middle fingers ought to be about 90 degrees. Experiment to see what works best. Three times your outstretched thumbtip to pinky finger- tip plus three closed middle fingers equals 90 degrees. Calibrating by the stars assures the greatest accuracy. No matter how close or far away an object is, ten feet or ten thousand lightyears, the angle subtended to you viewing those objects will be the same. A really sharp naked-eye astronomer can discern down to one arcminute. But I'm being conservative, so that ancient stargazers would need only resolve twenty arcminutes and estimate positions of stars and planets to plus or minus one de- gree, which for the Sun's apparent motion is about one day equals one degree. This is essential to know since adding one or more days to a predicted heliacal rising adds ~1 degree per day to the Sun's ecliptic longitude. Each consecutive heliacal rising for Mars occurs about 780 days apart. With a spectacular opposition for Mars just days away at this writing which will be August 27, 2003, Mars will rise heliacally about December 12 2004 at 26 Libra to the Sun 26 Scorpio. Mars will rise near 5:50 AM from my location with two marking stars rising above Mars, Zubenelgenubi at 20 Lib +0 & Zubeneshamali at 25 Lib +8. Add 780 days and we have January 31 2007. There's Mars at 16 Sagittarius to the Sun 16 Capricorn, 30 degrees apart. Mars rises locally about 6:40 AM. It is nearly impossible to see Kaus Borealis at 12 Sag -2 this close to sunrise (past astronomical twilight) and Mars may be difficult to spot here in the mountains of central Colorado. 16 Sag is 20 degrees past 26 Lib but we've witnessed Mars at opposition back on August 27th 2003 and again November 7, 2005, an 803-day difference. This also tells us that Mars is zipping along, so must have circuited the zodiac past 360 degrees, and is now 360 add 20 equals 380 degrees from where it was before. Simple interpolation tells us Mars takes some 739 days to complete one sidereal orbit. This is a rough figure as further observation shows. 10 times 780 is 7800. Ex- rience shows Mars has significant orbital eccentricity, and orbits quite rapidly through the caelestial zodiac. We find through experience that Mars is frequently off by a month or more from where we predicted it would be last we predicted its next heliacal rising, setting or any other repeating like-phase. Mars is at 14 Pis, and the Sun is 6 Ari on April 21, 2026. We must jump ahead to May 28, 2026, fully 37 days later, to find Mars and the Sun separated by 30 degrees sidereal longitude. As the apparent velocity of Mars is nearly as fast as the Sun's past superior conjunction it takes a few days to compensate for being just a degree off from 30 degrees. Thus to compensate for 8 degrees delta took us 37 days. Come May 28 2026, Mars is 12 Ari and the Sun is 12 Tau. Hamal at 13 Ari +10 and Sheratan at 9 Ari + 8 makes it easy to estimate Mars' position at 12 Aries. Shedir at 13 Ari +47 draws a nearly perpendicular line or arc to Hamal relative to the ecliptic making measurement easy. 26 Libra is 166 degrees from 12 Ari, meaning Mars went under eleven & a half times or 4126 degrees around the zodiac in 7837 days, making our observable average 684 days per sidereal orbit based on just two observations ten heliacal risings apart. Babylonians over centuries of observation and calibration found this to be around 687 days based on the long-term averages, which is one year, three hundred twenty-two days per sidereal orbit of Mars. These ancient astronomers-astrologers noticed that 151 sidereal orbits of Mars nearly coincided with 284 tropical years and 133 repeating synodic phases of Mars to the Sun. Add 284 years to December 12 2004 and we arrive at December 12, 2288. There's Mars at 23 Lib and the Sun 22 Sco, 29 degrees apart. Merely four days later finds Mars 26 Lib & Sun 26 Sco--right on the dot. So the ancient Babylonian sidereal-synodic multiple of Mars is off just 4 days in 284 years...very impressive. We also notice that Mars goes retrograde centered near inferior conjunction for an average of 73 days. Try it. Astrolog charts the synodic velocities of every planet. The presently-imminent opposition August 27 2003 shows Mars turned retrograde back on July 29, 2003, and will leave retrograde September 27 2003, a difference of 60 days. With every empirical observation for retrogrades and oppositions, the accuracy of this average improves. Observation proves 73 days is Mars' retrograde average. Next on the list is Earth, meaning the Sun relative to Earth. Since circa ~200,000 BC, the heliacal rising of stars has consistently demonstrated to stargazers that the tropical year precesses against the stars by about five-sixths of one arcminute per year or approximately one degree per 26000 solar days, i.e. 71 years 68 days on average. The ancient Mayans were superb astronomers. They used a "Haab" intercalation interval so that 1508 haabs was commensurate with around 1507 tropical years (C.P. Bowditch, published 1906) since the value of one mean tropical year takes 365.2422 mean solar days, and one Haab equals exactly 365 days--you do the math. The very long-term Mayan average for the great year of pre- cession equals 5 times 13 Baktun, or 5 ages of the Sun. Interesting, since Leo is the fifth sign of the zodiac. One Baktun is 144,000 days. 13 Baktun = 1,872,000 days. Five times 1,872,000 days equals 9,360,000 days a year of precession ergo one 360-degree sidereal gyration of Earth's axis of rotation against the caelestial zodiac takes some 25,626 years 303 days. From this we predict one zodiacal age of precession is 2,135 years 208 days. Cf. modern secular-religious estimates of ~2,150 years. The Mayan long-count is undoubtedly more accurate. The well-known date of December 21, 2012 was predicted not by modern science but by ancient Mayan astronomers. It predicted the winter solstice Sun conjunct the "sacred tree" or apparent intercept of the galactic & ecliptic planes at 5 Sagittarius +0...accurate to one arcminute. If we subtract 9360000 days from December 21 2012, the last conjunction of the winter solstice Sun was likely not too far from Julian Day -6903717, which the modern Gregorian calendar shows as March 1, 23615 BC, clearly way off the mark...the Gregorian calendar is erroneous for long-term prediction. The Mayan calendar is better by far but how they achieved such mastery is a mystery, unless they actually observed for many, many millennia. I believe this is how they did it, and that the Mayans and other pre-Columbian civilizations are vastly older than secular-religious archaeologists have admitted to. By watching the precession of Earth's axis, really the whole rotating Earth, long-term prediction of sidereal- synodic-tropical cycles gained accuracy over centuries and millennia of observation. The length of solar days was always the basis for counting longer periods, such as a lunar month was some 29 1/2 days, a tropical year was about 365 1/4 days, four tropical years about 1461 days etc. Each multiple was numbered by days, months & years, by the Sun the Moon & Stars also as per Genesis. Hence the multiples for the planets out to Saturn were referenced to Earth's solar days, lunar months and the Earth's tropical and sidereal years. As we've seen for Mars, Jupiter & Saturn, the sidereal motion of planets is fundamental to determining not only the position of a planet but also its sidereal year around the Sun. It is perfectly obvious that Mars, Jupiter & Saturn orbit the Sun and it is equally obvious that Mercury & Venus also orbit the Sun. Hence it follows that Earth orbits the Sun, since we can see that Mars is further away in its orbit than Earth is and Venus is closer than Earth is by its heliocentric orbit. Only the Moon sidereally appears to orbit the Earth, and the phases of the Moon show that both Earth and Moon are orbiting the Sun--in reference to the caelestial sphere. Incommensurability between Earth's tropical and sidereal years is easy to understand, yet has confounded more than a few amateur astronomers and astrologers for centuries to millennia. In tracking the synodic and sidereal motion of planets, we are referencing all positions, that of the Sun, and the planet(s) in question, to the caelestial zodiac of the stars. We are counting in solar days independently of years at first, only later by counting fractions of years in days instead of decimal places. Thus the side- real year of Earth reveals to an observer how tropical years are slightly faster than sidereal years, as year after year we see this disparity compounding enough so that we can correctly estimate the value of precession. The difference between a solar day and sidereal day on Earth is dependent on the length of a sidereal year vs. the length of a sidereal day. The faster Earth rotates sidereally, then the more solar days per sidereal year the observer will witness. The faster the Earth orbits the Sun, the fewer solar days per sidereal year we see. Since the tilt of Earth's axis circa 200,000 BC, solar days have numbered 365 and change per year with barely 50 arcseconds per year difference between sidereal and tropical year relative to the stars to wit, precession. That is why a solar day is slightly longer than a side- real day, since Earth's orbit makes the Sun rise later than distant stars which, comparatively, care not that Earth orbits the Sun with its sidereal-annual parallax having generally undiscernible effect, sidereal diurnal parallax/geocentric parallax having thousands of times less effect on the apparent positions of stars--albeit planets are affected slightly more, Moon more than any- thing else. At about a quarter million miles, the Moon can appear up to a degree off from geocentric position. So far we've looked at Saturn, Jupiter, Mars & the Sun. Next on the list is Venus, the venerated planet nearly the same size as Earth, and whose orbit is least eccen- tric of any planet in our solar system, with an almost perfectly circular orbit, proportionally just ~0.00677 between the major and minor axis although Venus orbits the Sun some three and a third degrees inclined to the Earth's ecliptic. All in all Venus has the most predic- table orbit of any planet in the solar system with the exception of Earth itself, whose orbit with the Sun is only about 0.0167 eccentric -- a ratio more than twice that of Venus. The Venusian orbit is around 72% as far from the Sun as Earth's orbit, hence has a faster side- real year of about 225 solar days, or about 61.5% that of Earth. Look at July 1, 2004. Venus rises heliacally at 15 Taurus, 30 degrees from the Sun 15 Gemini. Venus is about 4 degrees below the ecliptic, just one degree above Aldebaran (alpha Tau) at 15 Tau -5, and just one degree in longitude from Ain, epsilon Tau at 14 Tau -3. Venus'll rise approximately 4:40 AM MDT at my location. - From past experience we know that Venus takes 584 days to repeat its synodic phases. Add 584 days to July 1st 2004 and you have February 6th 2006, which is two days past 30 degrees from the Sun, so we have to back up to February 4th 2006, with Venus at 21 Sag and Sun 21 Cap. Venus will rise about 6 AM MST. In 582 days, Venus has moved from 15 Tau to 21 Sag, which is 576 degrees from Venus' last heliacal rising. Simple interpolation says that Venus will move 360 degrees against the stars per 364 days or near the period of the Sun's sidereal year to Earth. From our perspective on Earth, Venus appears to orbit the Sun epicyclically, so we can think of the planet Venus (and Mercury, which we'll cover later) as a "moon" of the Sun especially since Venus and Mercury are the only two planets in our solar system that have no moons of their own. The sidereal motion of Venus is easily rectified by watching every 5th heliacal rising, since 5 x 584 = 2920 days. Our past experience reveals that every 2919 to 2920 days Venus will appear to rise heliacally at about the same time of tropical year and against about the same background stars. Meaning every eight years, Venus will appear at about the same phase relative to the Sun and also in the sky (on the caeles- tial zodiac). Try it. Add 2920 days to July 1 2004 and you have June 29 2012. The Sun is 13 Gem, Venus 13 Tau, 30 degrees to the Sun and 2 degrees from 15 Tau. Venus has repeated 5 consecutive synodic orbits and about 13 sidereal orbits. Which means Venus has orbited the Sun 13 times in 2920 days making an average of 224 and six- tenths days per sidereal orbit--very close to the mark. Subsequent observations over decades to centuries will confirm that Venus' sidereal year is closer to 224 and seven-tenths mean solar Earth-days, this, according to ancient Babylonian astronomers cir. 1800 BC. They said 1871 sidereal periods of Venus is close to 720 synodic phases of Venus and 1151 tropical years on Earth. This is readily demonstrated by adding 1151 years to July 1, 2004, bringing us to July 1 3155. Try it. We must jump ahead 29 days to July 30, 3155. Venus is 27 Tau to the Sun 27 Gem. The default semisextile aspect 30 sidereal degrees between each planet and the Sun is the natural default for our planetary analysis of heliacal risings. Over 1871 orbits and we're off by half the zodiac from Venus 21 Sag to 27 Tau. That's 150 sidereal degrees we missed by using a Babylonian sidereal-synodic multiple for Venus. But wait! Out of almost two thousand orbits, being off by less than one orbit is actually very good, and being one month off in 1151 tropical years is also very impressive, and is subordinate to the 720 synodic repeating phases of Venus, thereby exact to one degree. The accuracy of the Babylonian multiple for Venus is a testament to their tremendous astronomical aptitude. I doubt that anyone before or since has presented a grea- ter degree of accuracy in their long-term ephemeris if you examine the actual evidence. Twice 1871 is 3742 or allegedly 2302 mean-tropical years on Earth, so try it. 2004 + 2302 = 4306. We already know that JPL's current estimates for tropical precession are off by 500 years per great year, thus it's no surprise we jump ahead to August 29 4306 with Venus some 30 degrees from the Sun. Venus is 10 Gem, and the Sun is 10 Can. Remember Venus was 15 Taurus on July 1, 2004. So we jumped ahead 2302 years to 4306. Venus and the Sun have moved 25 degrees ahead in 2302 years. The "Habb" intercalation interval tells us that the ancients figured 365.2422 days every tropical year, so 2302 years makes around 840,788 days. That's the long-term tropical-to-day interval, but the inference to Venus is also made, at 1151 years per 720 repeating phases. Hence 420,394 solar days ought to be about 1151 tropical years, and 1871 sidereal years for Venus is 30 degrees from the Sun, at regular intervals. We must show that a planet is visible to the naked eye, weather permitting, at moderate latitudes, at heliacal rising especially...by using 30 degrees as our default. This renders consistency to our empirical observations, even as rendered virtually by our modern computer soft- ware. We know it's accurate and we can thank dedicated astronomers for making such software possible and also commendably accurate and reliable. That's all fine and good. But let's not forget that these same astronomers have persistently ignored the ancient evidence for the astronomers throughout time, to be able to immediately see the sidereal and synodic orbits of the planets and be able to deduce which planets are closer and further away from the Sun, and also from Earth in their orbits. Anyone can see that the planets are not invisible, nor do they fail to show to their orbits to anyone looking, whether they looked at ten million BC or anytime since. Look at Julian Day 2453022 or January 17 2004 12 PM UT, with the Sun acquiring a semisextile aspect to Mercury of about 6 degrees with Sun in 2 Capricorn which is 24 degrees from Mercury 8 Sagittarius. Owing to Mercury's considerable ratio of orbital eccentricity, or about a fifth again larger between major and minor axis, we'll see Mercury rising heliacally at maximum elongation to the Sun, 6 degrees short of the 30 degree mark like we used for the other planets. Recall from my new book on Planetary Awareness Technique that Mercury needs to be at least 18 degrees separated from the Sun in order to become visible before sunrise or after sunset. Mercury never exceeds around 28 degrees of separation from the Sun in any case, so we'll never see 30 degrees between them. Mercury is seen to rise heliacally about 6:50 AM from my location, with Polis (muSgr) at 8 Sag +2 right next to Mercury, with Sabik (etOph) at 23 Sco +7 above right of Mercury. Bright red Antares (alSco) at 15 Sco and 5 degrees below the ecliptic points the way to the waning Moon at 2 Scorpio -1 and about 24% phase to the Sun. On the long-term average, Mercury will be seen to repeat its phases approximately every 116 days. We add 116 to January 17 2004 bringing us to November 10 2004. There's Mercury at 13 Scorpio to the Sun 24 Libra. But wait! Now Mercury's setting heliacally just 19 degrees from the Sun, at about 5:20 PM my local time, with the cascading Rocky Mountain 14-ers on the western horizon. But how did we go from heliacal rising to heliacal set- ting in just 116 days? It's because Mercury has a very high orbital eccentricity, and whose orbit is inclined to Earth's ecliptic by about 7 degrees. The centennial rate between consecutive Mercury perihelions increases by 573.57 arcseconds per century on this jpl/nasa site http://ssd.jpl.nasa.gov/elem_planets.html meaning that each consecutive perihelion advances by 5.7 seconds of arc each mean-tropical year. Cf. Earth's sidereal year of 365.25636 mean solar days, with Earth's anomalistic year of 365.25964 mean solar days per consecutive peri- helion, or five minutes longer than a sidereal year of the Earth-Sun barycenter, so that the perihelion point advances on average about 1.1 arcminutes per annum. At present, Earth's perihelion repeats around January 4th. Thus, Mercury's orbit is increasing ever so slowly out- wards from the Sun at a rate of about 61 miles per cen- tury (1 AU = 92,956,229.4 miles, Earth's mean distance from the Sun) or 6/10ths of a mile every tropical year. This also shows the orbit of Mercury increasing in its eccentricity by a ratio about 0.00002527 between major and minor orbital axis per century or about 0.00000025 per year on the semi-major axis of Mercury's orbit. By watching Mercury's heliacal phenomena over decades and centuries, a long-term average of 116 days is realized. We can jump ahead by ten synodic periods to see if our 116-day number holds up under scrutiny, bringing us to March 21 2007, since past experience has shown Mercury repeats ten average synodic phases closer to 1159 days, or 1 day less per every ten heliacal risings, settings etc. There's Mercury at 8 Aquarius to the Sun 6 Pisces, separated by 28 degrees in caelestial longitude, which is Mercury's maximum elongation from the Sun. Note the velocity fields in Astrolog, which shows the following: Astrolog 5.41G chart for Wed Mar 21, 2007 12:00:00pm (+0:00 GMT) 0W00:00 0N00:00 Body Location Latitude Velocity Sun : 5Pis36 +0:00'00" +0.9935813\ Mercury : 7Aqu53 -1:03'20" +0.9725359/ The following day, March 22nd shows Mercury's velocity to be overtaking the Sun's velocity, if only barely at +1.0177906 for Mercury, compared to the Sun +0.9929804. The velocity numbers tell how many degrees per day the object appears to be moving through the zodiac meaning the Sun is moving slower than Mercury is by March 22nd. Since Mercury appears to be moving slower than the Sun on March 21st, it follows that the angle of separation between Mercury & the Sun reaches its maximum on March 21, 2007, which is about 28 degrees sidereal longitude. Ancient Babylonian astronomers found that 191 sidereal orbits of Mercury lasted about 145 synodic periods and 46 tropical years. Try it. Add the 46 years to January 17th 2004, which will bring us to January 17, 2050. We find Mercury rising heliacally at 8 Sagittarius to the Sun at 2 Capricorn. As you'll recall Mercury was 8 Sag to the Sun 2 Cap back on January 17, 2004, making this ancient sidereal-synodic multiple for Mercury right on the money. You'll notice Mercury begin to overtake the Sun on the very next day, January 18 2050, which means that Mercury reaches its maximum elongation January 17, 2050. Clearly the Babylonians knew precisely what they were talking about--at least two thousand years before Christ. So much for the secularist "flat-earth" theory claiming that ancient astronomers didn't know that the Earth and other planets are in orbit around the Sun or their similarly-ridiculous contention that astronomers believed the world to be "flat" before the Johnny-come- lately Copernican astronomers figured out the contrary. The second-brightest object in the sky next to the Sun is the Earth's moon. Since time immemorial, humans and other hominids have watched the Moon wax and wane over the skies of Earth. The lunar orbit takes about 27 1/3 solar days to complete one sidereal revolution. That's more than two days faster than the lunar synodic month of about 29 1/2 days, and reveals to the observer that the phases of the Moon are a function of the Earth and Moon together orbiting the Sun. The Moon appears to be almost exactly the same size as the Sun as viewed from Earth, since the Moon is in fact 400 times smaller and 400 times closer than the Sun on average. This is easy to see during a total solar eclipse, during which time the Sun's corona becomes distinguishable from the dark background, and the Moon is seen to be closer to Earth than the Sun is. The relative distances of the Sun and Moon to Earth don't appear to change all that much and both Sun & Moon orbit Earth in a fairly linear fashion, albeit the Moon's orbit with the Earth is more complex. As a result, we can be sure that both Sun & Moon orbit the Earth sidereally. We already know from observation that the planets orbit the Sun, and we've also deduced the length of every planet's sidereal year and average synodic period. We've learned to count these repeating intervals by their observable averages in days, months and years, by their repeating synodic aspects relative to the Sun, and by their repeating sidereal aspects to fixed stars on the Earth's caelestial firmament. There- by we see that the Moon's phases take consistently lon- ger than the Moon's sidereal month by about 2 1/6 days. We have learned that the difference between the Moon's sidereal and synodic month is directly attributable to the length of a sidereal year of the Earth-Moon system orbiting the Sun verses the length of a sidereal month. We view the Moon orbiting Earth on a long-term average of some 13 1/3 sidereal lunar orbits per sidereal year, i.e. as seen against the fixed background of stars. Re- member, that the distant stars care not that Earth and the other planets orbit the Sun or more accurately the solar system barycenter along with the Sun, since even nearby stars a few dozen lightyears away are yet 1000s of times more distant than Earth is to the Sun. To wit, one lightyear is the linear equivalent of about 63,240 astronomical units where 1 AU equals ~92,956,230 miles, and just one lightyear equals ~5,878,482,160,000 miles. Even Spica (alpha Virginis at 29 Virgo -2, magnitude 1) at 262 lightyears is some 1 1/2 quadrillion miles from Earth...16.5 million times Earth's distance to the Sun. Hence Spica's trigonometric parallax is barely one one- hundredth of an arcsecond or nearly 5000 times smaller than one arcminute ergo undiscernable to the naked eye by a factor of five-thousand to one. If Spica were but one-twentieth of a single lightyear from Earth then we might barely be able to discern one arcminute parallax. At 2160 miles in diameter, and ~239,000 miles distance from Earth, the Moon's diurnal parallax can be as high as one arcdegree from its geocentric position. For the Moon, annual parallax has no effect, since the Moon is forever orbiting Earth epicyclically some 13 1/3 times per sidereal Earth-year. Thus the Earth-Moon system is averaging 360 divided by 13 1/3 makes about 27 degrees per sidereal month on average that the Earth-Moon bary- center has advanced in its heliocentric sidereal orbit. This means that the Sun advances on average 27 degrees per sidereal month through the caelestial zodiac along the plane of the ecliptic, and Moon orbits Earth about 387 sidereal degrees per synodic month totalling 12.37 synodic months per sidereal Earth-year. Eclipse cycles are tied to where the lunar orbit crosses the ecliptic, also called the nodical month, and is about 27.21 days. The anomalistic month averages 27.55 days which is the approximate interval between lunar perigees or apogees, and which determines an annular or total solar eclipse. There are numerous eclipse cycles running concurrently due to the complexity of the lunar orbit. Most popular of these are Saros cycles of 18 tropical years plus 10 or 11 days. Next comes the Moon's nutation cycle every 18.61 years, and is the average time that it takes for the head of the dragon, or north lunar node to regress full circle through the caelestial zodiac. Next is the so-called "Metonic" cycle, although Meton was far from the first one to have discovered this very predictable 19-year cycle. The ancient calendars revealed intimate knowledge of this cycle by its affect on intercalation, i.e. when an extra lunar month was computed in advance to make every second or third year have 13 months, not just 12 months as usual. This intercalation cycle runs every 19 lunisolar calendar years, following a pattern so perfect that it is off +two hours every 19 tropical years like clockwork. Two hours each 19-years added up to one extra day every 220 years or about ten days per zodiacal age ergo 10 extra days in 2135 tropical years. This enabled precise calculation of a calendar decades in advance by the tribal mathematician, the astrologer. This allowed ritual observance of seasonal holidays or holy-days in season and at the right phase of the Moon, all imperative considerations for calendar calculation, for planting, harvesting and all religious observances. We've seen how Earth's tilted axis results in tropical years, such that 1508 Mayan Haabs is commensurate with 1507 tropical years, meaning 1508 contiguous intervals of 365 mean solar days apiece total 550,420 solar days per every 1507 mean tropical years. This intercalation interval of the ancient Mayan calendar makes 365.24220 average solar days per average tropical year, which is an hairbreadth from modern averages i.e. less than one second in time difference per year between ancient and modern averages for a tropical year. 1 second per year. ^ ^^^^^^ ^^^ ^^^^ We've seen how the heliacal risings of stars & planets attest to planetary motion in our solar system visible to the unaided human eye. We've learned how to use the human hand to estimate subtended angles between planet and star readily to within one degree of longitude and latitude, and we know from experience that the best of naked-eye astronomers can discern as little as one arc- minute between objects. We've seen how a man can count by days, months and years to estimate repeating cycles of the planets, chiefly sidereal years relative to the Sun and distant stars, and by synodic aspects to Earth relative to the Sun. We've learned from experience how one sidereal year on Earth is barely 20 minutes longer than a tropical year, and that this tiny disparity can add up over time to the tune of one constellation--one zodiacal age--every 2,135 tropical years plus 208 days. There are longer eclipse cycles, like the Inex some 29 years minus 20 days. After this is the exeligmos cycle of 54 Years plus 34 days, basically three Saros cycles. There's an eclipse cycle each 58 Years less 40-42 days. Similar types of eclipses return every 65 Years plus 0 to 3 days. Then there's the triple Inex cycle every 87 years less 61 days. Beyond this is solar totality each approximately 410 years. Above this, 18 Inex cycles is 521 Years plus or minus 1 or 2 days and is very useful for making very long-term eclipse predictions. There's one longer luni-solar cycle which is called the "grand century of the Moon", and repeats like clockwork every 800 years. Lunar eclipses occulting the "bearded star" Regulus at 5 Leo recur in predictable, 800-year cycles. The last series ended in 1943, thus 2510 marks a point 567 years into this 800-year period, which is when the next eclipsed-Moon occulting Regulus series begins and lasts 233 more years, with a 19-year plus a 65-year se- paration between eclipse intervals which overlaps with metonic cycles of 19 years (235 solunar synods) and by similar eclipse-type cycles that repeat every 65 years. So 2510 AD marks the point 567 years + 233 years since the beginning of the last series in 1710. Backtracking in time shows that the last complete series ended 1143 AD, preceded by 343 AD, 458 BC, etc. Note here, Ezra's 7th year for king Artaxerxes was from October 2 458 BC through September 20 457 BC. This was year 3304 in the proleptic civil calendar which began October 1, 458 BC. Most notably, 458-457 BC was a grand jubilee year that always follows a 49th ecclesiastical "spring-to-spring" year in which all of the land lays fallow by Torah law. In Ezra 7:6-9 in the old testiment, 1 Abib was Tuesday, March 26, 457 BC, on which day Ezra left Babylon bound for Jerusalem--with achaemenid Persian king Artaxerxes' decree in hand. The first day of the fifth month found Ezra reaching Jerusalem, which was 1 Ab[Av] 3304, July 22, 457 BC which Ezra confirms is still in the seventh year of the gentile king as reckoned by the priesthood. The paramount importance plus astronomical historicity of these ancient calendar dates is thoroughly analyzed and documented in my book Historical Calendar Of Jesus, which, like all of my other books and articles, is pub- lished into the public domain on these usenet archives.
