# Thread: Equinox 2008

1. ## Equinox 2008

If a person could follow the orbital motion of the Earth,both the
Earth and the moon would show the same orientation to the central Sun
in terms of the solar radiation/orbital shadow boundary -

From an axial rotational orientation perspective you see this from
solstice to Equnox -

In a few days,the orbital orientation ,represented by the light/shadow
boundary (,seen in the first photograph), will align with the polar
axis and allied with axial rotation will generate a global symmetry
between daylight/darkness .Although you see the solar radiation/
orbita;l shadow boundary pivot off the Equator and close the
difference with the polar axis as the Equinox approaches,what is
actually occuring is that a location slowly turns through 360 degrees
with respect to the Sun over the course of an annual orbit and twice a
year,the motion of the boundary crosses the polar rotational axis.This
motion is quite apart from axial rotation.

So far,nobody has counted the reasoning of Copernicus in respect to
axial and orbital motion as one of the dramatic astronomical
experiences,putting observations in proper context in other words and
especially the motions of the Earth.Another Equinox goes by and with
all the incredible images availible to support the new orbital
component it still has not captured the imagination of people and that
is said with a touch of dismay.

Many definition will say the equinox occurs when the sun crosses the
celestial equator, but the correct definition is when the apparent
longitude of the sun is 0° or 180°.

Huh? The Moon doesn't have the same North Pole as the Earth.

This response shows that wormley is an idiot or an idibot..

However, since the apparent latitude of the Sun never exceeds a fraction
of an arc second, the difference between the two is at the most a few
ten seconds. Hardly anyone would notice the difference.... :-)

Another common definition will say the equinox occurs when "day and night
have the same length". This definition causes a much larger error in
the time of the equinox: a day or even several days, depending on your
definition of sunrise/sunset and also on your latitude. But at each
equinox, a number of people check their almanacs and get puzzled when
they find out that the day at equinox is slightly longer than the night.

No`offence to your geocentric outlook but I think people are ready
for modern imaging to put the Equinox event in terms of the
relationship between the axial and orbital motion of the Earth.The
magnificent motion which brings the solar radiation/orbital shadow
bounday in line with the rotational axis is due to the fact that a
location on Earth slowly turns through 360 degrees with respect to the
Sun over the course of an annual orbit.

It is highly unfair on the rest of humanity that descriptions based
on the pseudodynamic of variable axial inclination are still being
promoted when actual images resolve the issue in favor of an
additional component attached to the orbital motion of the Earth.I
would have nothing to gain from people who still use geocentric terms
and false graphical descriptions of the Equinox -

The images of Uranus which shows how a location turns through 360
degrees with respect to the Sun as a seperate motion to axial rotation
and tilt/orientation is meant to provide the conclusive affirmation of
what is observed of the Earth as that video shows

http://www.apl.ucl.ac.uk/iopw/uranus_keck_rings.gif

The Earth does not orbit the Sun like a train on a track but for any
given location,apart from axial rotation,will swing around through 360
degrees with respect to the Sun over the course of an annual
orbit.Allied with axial rotation it causes seasonal variations in
daylight/darkness and the global unequal noon cycles and many,many
other productive things.

There is no reason to be dismayed over the setting aside of variable
axial inclination to the orbital plane/Sun when there is a new motion
to look at and enjoy.

Just goes to show that you have no appreciation for the difference
between daylight/darkness and the natural variations in the natural
noon cycle.Both of these affects require a new motion to explain them.

The original explation for variations in daylight/darkness based on
variable axial/equatorial inclination was by Copernicus himself -

"..the equator and the earth's axis must be understood to have a
variable inclination. For if they stayed at a constant angle, and were
affected exclusively by the motion of the center, no inequality of
days and nights would be observed."
Copernicus Chapter 11 De Revolutionibus

http://webexhibits.org/calendars/yea...opernicus.html

That is a straightforward statement of variable axial/equatorial
inclination and how most people have learned about what causes the
change in seasons.It is also incorrect.

It may be easier to explain what is occuring by shifting the focus to
the global unequal length of the natural noon cycles and what causes
that.Everywhere on the planet experiences the same unequal length of
the natural noon cycles whether it is summer in the Northern
hemisphere and winter in the Southern or visa versa.The cause of the
variations in the noon cycles is due to two motions,axial rotation
and the change in the orbital orientation of a location with respect
to the Sun.Axial rotation is constant but orbital orientation change
is in accordance with Keplerian orbital motion.

The Earth rotates at a constant rate using the Sun and noon as a
benchmark ,there is a counter motion attached to orbital motion which
affects how long it takes axial location to return to noon.The
Equation of Time, which creates the idea of 'constant' axial rotation,
reflects the rate of change of orbital orientation from one cycle to
the next using constant axial rotation and natural noon as a
benchmark.

The alignment of the solar radiation/orbital shadow boundary with the
rotational axis of the planet reflect the way a location orbitally
turns with respect to the Sun,the change being not due to the boundary
itself but rather the underlying motion which closes the gap between
the SR/OS boundary and the rotational axis as the Equinox approaches.
