    Lunar Exercise
    From: Jeremy C
    Date: 2008 Sep 23, 14:21 -0700

    I was playing with my new sextant here  and got the oppurtunity to
    shoot a land lunar.  My paper calculation had a bit more error then
    Frank's web calculator, but perhaps I was doing something wrong with
    one or both of them.  I will have to re-run the numbers.  Here is the
    Lunar if anyone is interested in working it.
    
    A Lunar Exercise:
    
        Our intrepid Navigator is wandering through the city of Wilkes-Barre,
    PA, USA.  He wanders upon a stone in the public square that states the
    following:  Latitude 41 deg 14 min 40.4 sec North, Longitude EAST OF
    WASHINGTON, DC is  1 deg  10min  4.5 sec.  The Longitude of the Mall
    in Washington DC is 77 deg 02.2 min West.
    
        A series of near limb lunars is taken at the stone between the sun
    and the waning crescent moon.  Index error is 0.2� on the arc.
    Temperature is 66 deg F, pressure is 30.50 inches of mercury.  A
    uncorrected watch (ie no GMT) was used and the lunars were made over a
    period of about 5 minutes centered on 1545 UTC.
    
    Lunar Distance on the Sextant (LDs)
    
    71 deg 06.7�
    71 deg 05.7�
    71 deg 06.0�
    71 deg 06.0�
    71 deg 06.7�
    71 deg 06.0�
    71 deg 04.9�
    71 deg 04.8�
    71 deg 04.2�
    71 deg 04.5�
    
        Average the lunars and find UTC.
