    Re: Lunar Distance Puzzle

    Wow! Very close, very quickly!

    To generate the problem, I used:

    03 27 00

    38 53 24 N

    77 10 12 W

    My solution was:

    3 27 03

    38 56 23

    77 11 39


    It is, as was pointed out, sensitive to refraction. I used:

    R= 58.276" tan (90-h)-0.0824" tan^3 (90-h), where h is true alt.

    Impressive work on your part!
