    Default 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.

    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 -

    http://upload.wikimedia.org/wikipedi...quinox_EN..png

    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

    http://www.youtube.com/watch?v=nwTrYVBcx9s

    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.
