Planet X: Slowing Rotation 2 (Equinox Evidence)

2. If the Earth’s rotation is slowing beyond what is being admitted,
   then the time between Equinoxes should be increasing.  Yet this seems at
   first blush for any given year to be holding steady.

BUT, a close analysis of Equinox times show a trend toward lengthening
between Equinoxes, and a dramatic increase since 1983!

2a: Troubled Times member Mike describes confusion about tracking the
    Equinox, as the sun crosses the Equator at different places, often over
    the ocean, and moves about from year to year and season to season.

    Perihelion occurs typically on January 2-4 for each year. 
    Equinox will occur at the same UT time for everyone on
    the planet. Equinox occurs 1/4 of a rotation latter in 
    March 20-21 and was reported to the nearest minute. 
    Some people (about half) will be in the dark and some
    will be in the light at the time. The sun will only 
    cross through the ecliptic twice a year, March and
    September of each year. It is daylight on the side 
    earth that is facing the sun at the time of the crossing
    Equinox date/time stamp does refer back to Greenwich
    Longitude which is a standard "place" so to speak, 
    however, it could be dark or light on that side of the 
    planet at the exact time of the Equinox. It is random.
    The facing or crossing over concept is called "Transit"
    in the terminology of Astronomy. For example a 
    person standing on earth at a particular point has a 
    transit of the sun at or around noon time (local time).
    This concept should not be confused with the sun 
    crossing the equator which could be at any point on 
    the equator each time it happens. A different name 
    (equinox) was given to this condition of sun crossing 
    the equator of earth to distinguish it from other 
    concepts.

2b: Troubled Times member Mike found that the Navy had changed their
    forumula for computing Equinox, as noted in their Astronomical Almanac

    Astronomical Almanac 2001 
    Updates and Corrections
        Page B6, The equation of the equinoxes and the 
        paragraph following should read: 
           equation of equinoxes = 1/15(Dy cose + 0."002 64 
                                   sin W + 0."000 063 sin 2W)
        and Dy is the total nutation in longitude, e is the mean 
        obliquity of the ecliptic and W is the mean longitude 
        of the ascending node of the Moon. The equation of 
        the equinoxes is tabulated on pages B8-B15 at 0hUT
        for each day and should be interpolated to the 
        required time if full precision is required.

2c: Troubled Times member Mike charted the Equinox from Navy data and
    found is had been coming LATE up until 1983, whense it started, per the
    data at least, coming EARLY!

     trend ... last 52 years (1950-2001) ... +1.12 sec/year
     trend ... last 42 years (1960-2001) ... +0.92 sec/year
     trend ... last 32 years (1970-2001) ... +3.43 sec/year
     trend ... last 22 years (1980-2001) ... +7.99 sec/year
     trend ... last 12 years (1990-2001) ... +31.2 sec/year
    (chart at http://www.zetatalk.com/theword/tworx377.htm)

And the Zetas explained:

    The Equinox is computed, by the Navy, and only 
    actually measured every 4 years (in accordance with 
    leap year syncing). This is because during the 4 years
    that it takes to complete a leap year cycle, the Equinox
    per definition is around the globe, probably 1/4 turn 
    each turn or so each year for a given Spring or Fall
    Equinox. Why don't they do an actual measure as it 
    goes around the globe? Because most of the equator, 
    or a good part of it, is over ocean. To measure the 
    exact split second that the sun tips over the equator 
    would require more stability than a ship can provide. 
    Wave bobble, and the ship to be certain it is at the 
    exact coordinates must use guidance systems that 
    could be off a hair, etc. So they rely on a computated
    Equinox for 3 out of 4 years. But then they do 
    measure the Equinox from a set physical land 
    position, every four years, and this is what is late
    to arrive (at that physical point!).
