    Re: USCG Student Sample Problem #3 for East Longitude

    Hello Greg,

    Using ASTROLAB with your data (plus ACRUX Dec = 63° 5.94'S), I got the following results :

    DIPHDA + ACRUX + JUPITER : 25° 10.2'S 178° 40.9'E, radius = 0.15 NM
    MOON + SUN (5 hours later): 25° 26.1'S 176° 51'E
    5 sights with transport : 25° 28.5'S 176° 54.6'E, radius = 2.2 NM (!)

    The last line integrates a shift of near 94 NM between Jupiter and Moon sights !
    DOP is 1.9 for the 3 first sights, and is reduced to 1.4 for 5 sights.

    Regards,

    Yves Robin-Jouan
