"What, by the way, do the letters LAM stand for?"

 

 

A term my compatriot and I came up with late one night in the Caribbean Sea while shooting high altitude moon lines for circles of equal altitude.  Instead of "Local Apparent Noon" we made up "Local Apparent Moon" instead.  A bit silly perhaps, but methinks that we should be glad that two 20-something kids were enthusiastic enough to actually be out at night shooting LOP's by the light of the full moon.

 

The error in the one recent sight is indeed a typo in my transcription although in altitude while typing, and not in the shooting.  I have corrected it in another post.

 

As something to note George, I can consistently obtain star fixes in rolls of 15-20 degrees with accuracies of under 1.0 mile.  My lunars suffer a bit, so instead of 0.3', I am getting 0.6 arc minute errors.  There is a technique to shooting in large seas; and with good timing, accuracy can be maintained.  Your mileage may vary in small boats in which I have no experience.
