    My first Lunar
    From: Jeremy C
    Date: 2008 Jul 15, 17:25 -0700

    Well I found my first lunar, and it will be tricky.  Here's the data
    that I have.
    GMT Date is 26 January 1999.  GMT of the sight was about 2220.  Dip
    correction is -7.7' of arc.  The lunar was at evening twilight and a
    near limb observation between Jupiter and the Moon was taken.  The
    sextant LD is 68deg 19.4'  IC is 0.0'.  An upper limb altitude of the
    moon was taken HS is 66 deg 09.3'  The Hs of Jupiter is 45 deg 22.3.
    Here's the rub:  I have no idea where I was other then to say I was
    probably somewhere in the Eastern Caribbean.  Best guess is about 20
    deg North Latitude and 70 degrees West Longitude.
    Let the figuring (and debating) begin!
    PS If I left some critical piece of data out, let me know and I will
    review my worksheet.
