Default Solstice December 2018

The great forward motion of the Earth through space has turned the North and South Poles to their appointed positions on the Solstice -

The area where the Sun is constantly in view is about to reach its maximum circumference (Antarctic circle) while its Northern counterpart the opposite is in operation.

At lower latitudes, apart from the Equator, the maximum asymmetries between daylight and darkness are reached before the balances shifts after the Solstice and the slow leveling goes on towards the Equinoxes as the Poles and the entire surface of the Earth turns parallel to the orbital plane.

The people who dump everything into circumpolar motion may not care, however, those who can look into the centre of the solar system and towards our stationary Sun can see the full relationship between our motion and that Sun along with the motion of the faster moving planets -

However grainy that time lapse is, to see the stars move in isolation and parallel to the orbital plane, it is a true masterpiece for those who genuinely love astronomy.
