    Douglas's posting stated 2008 as the year, which is what I used.  I missed that another line in the same posting says 2009.  For 2009 I find from my aries_stars.xls spreadsheet:

    GHA:  81 degrees 49.7'
    Dec: S 29 degrees 34.0'

    My second source was Frank's online almanac.
    So I suppose that this answers my question. :-)

    I seem to find GHA=81 deg 49.6 min and Dec= S 29 deg 34.0 min at 9:00:00 UT on 13 July 2009 in all of the following sources:

    USNO online navigation data
    USNO ICE program
    Frank's online almanac
    Andres Ruiz's almanac program
    Xephem program


    Can you name yours?

    (I get close to your answers for 9:01:00 UT.)
