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
