September Equinox 2014
There are so many variants on the 'tilt' of the Earth or the motion of the Sun North and South within a rotating celestial sphere,some are unintentionally funny more than others -
"It has begun to feel like fall, with schools in session and a chill in the air, but the season actually arrives at the moment of autumnal equinox at 10:29 p.m. Monday. At that instant, Earth will be rotating upright on its axis, giving the northern and southern hemispheres equal sunlight and making the length of day and night roughly equal. In Baltimore, the sun will stay up for 12 hours or more until Friday." http://www.baltimoresun.com/news/wea...,7067415.story I do not fault this guy no more than I fault anyone here, the whole idea of bringing attention to the Equinox relies on recognizing the surface rotation to the central Sun generated by the specific way the Earth moves through space and around the Sun. Isolating the orbital surface rotation is problematic insofar as 'axial precession' is so ingrained as a perspective that it may be difficult for many to make the transition to the more productive view even when observers can see Uranus 'precessing' across its 8 decade orbit of the Sun - http://londonastronomer.files.wordpr..._2001-2007.jpg Tomorrow I will go down to an area on the East coast of Ireland where, if clear skies permit, I will watch the Sun rise in front of the entrance of a cave which is imitated inland via Loughcrew and Knowth at the Equinox and Newgrange at the Solstice. It is my own private Equinox spectacle in an area once inhabited by astronomers 5200 years ago. http://www.knowth.com/loughcrew-equinox.htm These were the true astronomical modelers for had observers today being paying attention they would quickly discover that the age of Newgrange and Stonehenge are many centuries apart but still retain their Solstice alignments despite being roughly 20% through a precessional cycle so the perspective which arose from the time of Copernicus does not hold. Of course I know why but this is another day's work. |

You are using your incorrect definition of 'axial precession', which is meaningless the way you use it. You don't get to hijack definitions, it just makes you look increasingly stupid.

This has nothing to do with you, you live in a celestial sphere bubble which disqualifies you from discerning what is,in fact, a 100% observational certainty - http://londonastronomer.files.wordpr..._2001-2007.jpg The forward motion of the Earth through space has the same surface rotation feature to the central Sun hence call me what you will, it will be there for all those who really wish to appreciate dual surface rotations which make up the seasons, why noon cycles vary and all the other features which emerge by using these dual rotations separately or in combination.

September Equinox 2014
One of the most dismaying images of the Earth from space is the 'tilting' circle of illumination -
http://earthobservatory.nasa.gov/IOTD/view.php?id=52248 As the Earth moves through space the circle of illumination always remains at right angles to the orbital plane as any reasonable person would expect. Because of its distance from Earth and to the central Sun we do not see the circle of illumination of Uranus but all planets have that feature created by solar system geometry and the light of the Sun - http://www.masil-astro-imaging.com/S...age%20flat.jpg 'Tilting' the circle of illumination or indeed the Earth towards and away from the Sun is simply a symptom of an ideology which does not take the single annual surface rotation of the Earth to the Sun into account arising from the specific way the Earth travels through space. There is no reason whatsoever that the space agency cannot scramble together images of the Earth as it turns to the Sun just as those images of Uranus indicate. |

Is the surface rotation as a function of the Earth's orbital motion alone so repulsive or so difficult to understand that people would choose to follow a 'tilting' circle of illumination or the motion of the Sun North/South within a celestial sphere ?. I can tell you all about isolation but never has such a beautiful sunny day like today felt so wasted as among people who would fill this world with doom if they were let. |

That's fine, we all know there is a secondary rotation due to the earth's journey around the Sun, but to call it 'axial precession' is incorrect on your part, and that is just what you are doing. |

The structure of Loughcrew is much less glamorous than Knowth or Newgrange yet to witness the light hit the recess as they did so many years ago is as wonderful now as it would have been back then and the fact that anyone can enter the chamber makes it an experience for any astronomer - https://www.youtube.com/watch?v=qIv-zm9Yfu4 Like astronomical and terrestrial events,all things human come in season and diminish in season and perhaps that is why I felt today more than any other personally and as an astronomer. All the same there are genuine good things ahead when men don't doctor imaging to suit a conclusion but allow the imaging to dictate a visual narrative. |
