    Re: nautical almanac first point of aries
    From: Robert Bernecky
    Date: 2012 Mar 12, 13:57 -0700

    Just to practice using the NA's tables I just did this experiment
    When my computer's clock ticked to 2012 Mar 12 04:45:46 pm EDT or
    2012 Mar 12 20:45:46 Z
    I asked the tycho site http://tycho.usno.navy.mil/cgi-bin/sidereal-post.sh for LAST
    It returned 08:09:21.5 LST

    According to the NA on 2012 Mar 12 2000Z Aries was 110º 52.0'
    Using the table of increments and corrections 45m46s 11º 28.4'
    or 122º 20.4'

    Using the table Conversion of Arc to Time
    122º 08h 08m
    20.5' 1m 22s
    or 08:09:22 which matches as well as can be expected with tycho.
