    Moon sight?
    From: Samuel L
    Date: 2014 Oct 3, 20:24 -0700

    I took my first sight on the Moon last night (10/3/14) at 00:26:20 GMT.

    In working through the sight reduction all went reasonably well except when it came to the sextant correction work.

    The Moon's HP was 59.3

    Here's what I did;

    HS- 62d 3.9min

    IE -0.1min

    Ha divided by 2 (since using an AH) 31d 1min 54sec

    Main correction= +47.4min

    Lower Limb= +5.9min

    Refraction= -1.7min

    Moon's SD= +16.3min

    Ho= 32d 9.8min

    Are there any other corrections that are to be applied that I've not included here?

    The resulting LOP gets me within about 2 miles of the Ap Longitude (W 075d 45.6min)

    Thank you,

    Sam
