    Re: An exotic lunar distance puzzle
    From: Greg Rudzinski

    One last LOP to do for the Exotic Puzzle is the distance short of the horizon.

    Formula: Distance NM = Height of Eye NM/SIN(Altitude) x COS (Altitude)

    Altitude = Dip + Hs measured from horizon down to object.

    For this puzzle:

    H.E.= 221 NM
    Dip= 18* 18'
    Hs=7* 24'
    Alt = 25* 42'

    460 NM = 221 NM / SIN 25.7* x COS 25.7*

    This result is consistent with the other terrestrial LOP's further confirming the cities in question as Grand Island and Hastings.
