The analemma is a disruptive hoax that is preventing necessary modifications from making it into wider circulation. There is nothing left to say,if the scientific community,should it wish to call itself that,is determined to remain stuck with a wandering Sun explained by the daily and orbital motions of the Earth then it condemns itself to a condition of irrelevance as the budget for such a ridiculous analemma ideology is nil.The true wanderers,the planets, and their wandering motion will continue to be the only valid perspective and the resolution for retrogrades is the main argument for the Earth's orbital motion between Venus and Mars but I don't need to go that far,do I. Very different feeling knowing that we all are looking at the same picture and especially the use of modern imaging to counter the analemma distraction with the main Western astronomical insight that uses the wandering motions of the planets to account for our own orbital motion,each wandering motion different than the next yet all telling the same great story - http://apod.nasa.gov/apod/ap100613.html The wider world needs a few points of rest where it can enjoy genuine achievements such as that of Copernicus and we just don;t need a useless ideology of a wandering analemma Sun competing for attention with the true wanderers - the planets. |

I am no longer giving people a choice because there really isn't any - planetary retrogrades and their resolution or nothing at all. We all agree with Copernicus' and Kepler's resolution of planetary retrogades as an illusion caused by the Earth's orbital motion around the Sun. So we don't need a "choice" there, as there is no disagreement. We use clockwork to follow the motions of the Earth and the other planets because the planets and the stars, while in the "heavens", are still part of the world, like the Earth. The celestial realm is *not* the Heavenly realm, the abode of God and His angels - that is beyond our physical reality, and it is not possible to see that with a telescope. So it is no debasement for Newton to use the same laws that apply to shooting cannonballs to explain the Moon's orbit - the Moon is part of the physical world, not the spiritual world. John Savard |

If you think the analemma is a 'hoax', then you don't really understand it (or pretend not to). Hint: it has absolutely *nothing* to do with wandering planets (or a 'wandering Sun'). |

If you think the analemma is a 'hoax', then you don't really understand it (or pretend not to). I have a few proofreading issues and a few technical details to clear up and not least the modification to 'axial precession' as it is currently classed and analysed. The motion of the Sun is seen to move from horizon to horizon in a direct way as it scribes greater or smaller arcs depending on where the Earth is in its orbital cycle ,there is no figure '8',just a continuous spiral captured in this contemporary sequential imaging as the Earth turns in its daily cycle and simultaneously,yet separately,makes a circuit of the Sun - http://apod.nasa.gov/apod/ap120121.html The analemma is a distraction as it tries to impose an alternative structure through timekeeping averages so what would normally be a harmless exercise for photographers turns into a disruptive hoax which prevents a clearer view of what causes the seasons and variations in the natural noon cycles. Hint: it has absolutely *nothing* to do with wandering planets (or a 'wandering Sun'). The annual variations in the height of the Sun from June to December require an additional orbital component which amounts to a traveling axis around which the polar coordinates turn to the central Sun.The components of the daily rotational characteristics and the orbital components are contained in the following graphic - http://www.simpletoremember.com/imag...ds/erthaxs.jpg The discontinuous line represents the orbital characteristics of a traveling axis running through the center of the Earth from Arctic to Antarctic circles with an orthogonal line running through the center of the Earth from roughly he tropic of Cancer to the tropic of Capricorn.The polar coordinates turn in a circle about the discontinuous line so this explains why at the North/South poles they turn through the circle of illumination at the equinoxes which divide 6 months of daylight from 6 months of darkness depending on where the Earth is in its orbital cycle.Ignoring the direction of the arrows,the annual precession of the polar coordinates to the central Sun is more or less like this - http://upload.wikimedia.org/wikipedi...precession.svg It is a quasi-rotation as it originates from the orbital behavior of the Earth and the polar coordinates act like a beacon or a window into the orbital behavior of the planet.A simple imitation analogy with a broom handle substituting for the daily rotation of the Earth in fixing it constantly to an external point at 23 1/2 degrees off the line of your body as you walk/orbit a central object/Sun will show that the tip of the broom will precess to the central Sun about the orbital axis formed by the line of your body and seen in the earlier graphic as a discontinuous line. http://www.simpletoremember.com/imag...ds/erthaxs.jpg If the graphic above expressed the June Solstice with the Sun to the right,the angle between the rotational axis and the line orthogonal to the orbital axis is acute hence the Sun scribes a large arc from horizon to horizon and, half an annual circuit later, as the Northern polar coordinates turn around to the December orbital point,the angle between the rotational axis and the orbital line becomes obtuse hence smaller arcs.At the equinox as the polar coordinates turn to split the circle of illumination and mid-way between the greater and smaller arcs,the rotational axis lines up with the orbital axis from a view consistent with the other two descriptions using the graphic above. No figure '8' Sun distracting from daily and orbital dynamics and the new approach to the reason we have the seasons and the variations in the natural noon cycle.It deserves a formal presentation but unfortunately I have no way of knowing at what level these things are understood even when cross referencing using images of other planets is more than sufficient to arrive at common principles and motivate astronomers to adapting to the new approach.This was never an exercise in disproving a hoax like the analemma,it was a much weightier matter of adjusting 'axial precession' to an orbital feature thereby easing the strain on explaining the seasons properly. |

Since the Earth's *mean solar day* is almost exactly 24 hours, an analemma can be traced by plotting the position of the Sun as viewed from a fixed position on Earth at the same clock time every day for an entire year. The resulting curve resembles a lemniscate of Bernoulli. This curve is commonly printed on globes, usually in the eastern Pacific Ocean, the only large tropical region with very little land. It is possible, though challenging, to photograph the analemma, by leaving the camera in a fixed position for an entire year and snapping images on 24-hour intervals (or some multiple thereof). |
