Default March Equinox 2011


The orbital daylight/darkness cycle and the fascinating way the Earth
orbits the Sun using an axis stretching through the center of the
Earth from Arctic to Antarctic circle requires a formal setting,in an
era where the Earth is seen from space there is no excuse for
ignoring the dynamic which causes the polar coordinates to turn
through the circle of illumination whereby one side of the Earth turns
to the Sun for 6 months and the other side turns away for 6 months .

Having very clear and decisive ideas are fine so long as there are
enough readers who can deal with the correspondence between cause and
effect and there is nothing to indicate that the technical issues
which introduce an additional orbital component is in anyway difficult
in acknowledging as cause and effect and unfamiliarity is no longer an
issue either.

Time to move on guys,modern imaging demands it in getting rid of those
awkward descriptions of the Equinox event which do not incorporate the
orbital day/night cycle and its cause -

"An equinox occurs twice a year, when the tilt of the Earth's axis is
inclined neither away from nor towards the Sun, the center of the Sun
being in the same plane as the Earth's equator. The term equinox can
also be used in a broader sense, meaning the date when such a passage
happens."

http://en.wikipedia.org/wiki/Equinox

The modified explanation is that the Equinox is an orbital event where
the Earth orbitally turns to the central Sun in bringing the polar
coordinates in line with the circle of illumination and orthogonal to
the central Sun.This requires a formal setting rather than the serious
misadventure of trying to ignore both the orbital day/night effect and
its orbital cause.
