    Date: 2008 Dec 25, 10:59 +0100
    In [NavList 6768] and [NavList 6796] Frank and Dave gave us the graphical solution.
    Here is the analitical one.

    For the planets the SD and Parallax(HP) corrections to clear the LD haven`t taken into account.
    Venus
    01/12/2008 20:00:00
    GHA = 75.998065 º =  75º 59.9'
    Dec = -23.870384 º = -23º 52.2'
    SD  = 0.138659 '
    HP  = 0.146132 '
     
    Jupiter
    01/12/2008 20:00:00
    GHA = 76.849810 º =  76º 51.0'
    Dec = -21.960804 º = -21º 57.6'
    SD  = 0.282741 '
    HP  = 0.025225 '

    If you grabbed your sextent (or your octant, or your quadrant, or your protractor and string) and made the following near limb distance observations at 20:00:00 UT 2008 Dec 1: Venus 1 deg 16.9 min, Jupiter 1 deg 35.3 min, what island would you be near?
