September Equinox 2015

Unfortunately the teaching community still hasn't come around to explaining the seasons properly by splitting the cause into two separate daylight/darkness cycles and their respective rotations to the central Sun.

As the Earth move through space and around the Sun, it turns unevenly so that presently the North and South polar latitudes now are positioned close to the circle of illumination creating the respective orbital dawn in the Southern hemisphere and approaching orbital twilight at the North pole. These latitudes exist roughly 23 1/2 degrees above the fully illuminated face as determined by the Earth's orbital plane.

So we have the normal daily daylight/darkness cycle due to diurnal rotation and at habitable latitudes closer to the Equator and temperatures respond to the appearance and disappearance of the Sun and solar radiation each 24 hours and then there is the long term temperature fluctuations owing to the orbital surface rotation and experienced as the seasons split between hemispheres.

The days of trying to explain the Earth tilting towards and away from the Sun causing summer and winter should be over as common sense prevails and 21st century people consider the seasons from the perspective of the two known daylight/darkness cycles and their underlying cause. There is also the variations in the natural noon cycles to consider owing to the same dynamical causes.

It is also a lot of fun with the new approach and kids will love it.

One crucial out of sight in that time lapse footage, for obvious reasons due to distance from the Earth, is the circle of illumination.

The triumph of contemporary imaging is appreciation the dual surface rotations directly and particularly the uneven rotation of the planet to the central Sun as it moves along its orbital circumference with the 4 years of footage condensed into a few wonderful seconds.

The entire Earth turns likewise however it is at the North and South poles as orbital dawn enters at the Southern latitude and orbital twilight begins to set in at the Northern that genuine astronomers get a feel for what is new and what is productive.

How is the Hubble telescope pointed. Thank Newton's laws:

Celebrate your heretical religion by yourself. Don't keep posting
inanities. We know it's coming up to your Holy day but we don't care.

Orbital dawn has arrived at the Southern polar latitude which is 23 1/2 degrees above the fully illuminated face of the Earth as determined by the orbital plane.

This is not 100 years ago or 300 years ago where academics are allowed to die off before something new appears, this is the 21st century where insights come rapidly and nobody has to wait on sanction from academics who are way behind in using contemporary tools.

The Earth has two separate rotations to the central Sun corresponding to two distinct daylight/darkness cycles. The combination of these two rotational cycles we call the seasons at habitable latitudes.

Most people are familiar with the development of frost and road ice as the planet turns away from the central Sun daily and the melting as that location rotates back into solar radiation.

The development and disappearance of Arctic sea ice also is dependent on a surface rotation to the central Sun only this time it is a function of the orbital motion of the Earth through space.

So, wonderful thing it is to realize that most people experience dual temperature fluctuations in response to dual surface rotations. The Earth does not tilt towards and away from the Sun, it turns in two distinct ways and the sooner the explanation for the seasons makes it into wider circulation the better as variations in inclination between different planets is crucial for determining planetary climate.

I had a look at how NASA explained the Equinox -

" Explanation: When does the line between day and night become vertical? Tomorrow. Tomorrow is an equinox on planet Earth, a time of year when day and night are most nearly equal. At an equinox, the Earth's terminator -- the dividing line between day and night -- becomes vertical and connects the north and south poles." NASA

It never works to attack people or organizations but rather to gently guide people who do really wish to know what leads to an Equinox event. In this case there would be imaging that shows the North and South polar latitudes 23 1/2 degrees above the fully illuminated face of the Earth as determined by the orbital plane and a constantly vertical circle of illumination.

It is a simple matter of dividing the dual daylight/darkness cycles into separate causes and combing them at lower latitudes where they play out as the hemispherical seasons.

It is quite an experience to go through all the various and hopeless ways to describe the Equinox event using with the common theme of a tilting Earth.. The worst explanations,if they can be called that, happen to be from the major organizations who have adopted an RA/Dec cult view of the 'Sun being on the Equator' moving South or North.

So every year I come here and expect to see the proper explanation which splits the experience on the surface of the planet to the two known daylight/darkness cycles going on simultaneously. A person at the North or South polar latitudes see the Sun rise once a year followed by the appearance of the stars for roughly 6 months and the rotation behind this observation is a function of the Earth's orbital motion through space.

I don't know why people won't accept the dual surface rotations even though I well know the problems created by extraneous views which influence observers since Copernicus. The missing feature in the following time lapse footage is the circle of illumination due to the distance between the Earth and that planet however that planet turns in two separate ways as it moves through space along with daily rotation as we know it -

On a personal note, the Saturday afternoon I came to understand what was needed to break the awkward viewpoint based on 'tilt' was one of the hardest conundrums to crack but for a single instance I got a glimpse of the solution and have built on that including not only what causes the Solstices and Equinoxes but also the variations in the natural noon cycle.

Of course people with convictions and no intelligence lack grace and style to work their way to a better explanation of these things.

Again, the Middle Eastern thugs are gentlemen compared to the thugs currently destroying Western society from the inside, after all the Middle Eastern brutes blow up an ancient heritage which can't be replaced while the empiricists destroy a working astronomical heritage and especially the attempt to obliterate the Lat/Long system which refers the Earth's rotation to the 24 hour AM/PM system.

There is no reasoning with thugs, there is only the historical and technical veracity which keeps rotations fixed to the orbital points by introducing an extra rotation after 4 cycles of 365 days and rotations.

With this particular topic the issue of distinct daylight/darkness cycles arising from separate surface rotations is being subverted by the contemptible notion that the Earth has separate surface rotations using the same cause via a 'solar vs sidereal fiction. This is pure and utter thuggery surfaces with the notion of more sunrises/sunsets than rotations and that is intellectual and conceptual hell.

All the great attributes of humanity such as courage, bravery, delight in achievement, innovation and all those things which elevate the spirit is absent with brutes for they never really live and are seen for the dour and dismal creatures they actually are.
