As I was sitting in the hot tub this AM watching the spectacular heavens with the moon and venus about 15 degrees apart, it occurred to me to wonder about lunar distance measurements using venus. I've never tried to measure any lunar distances but I went ahead anyway. My results were consistently about 5 to 7 minutes lower than predicted by a program I wrote that uses the Mosier JPL AA routines. I wonder if this is some fault in my measurements, calculations, or the AA routines. I'd really appreciate it if someone could independently work out the moon venus distance for 89.50 west 42.85 north altitude 290 meters temperature 5 degrees C tick.usno.navy.mil time 6-13-06 CDT 11-13-06 Greenwich I assumed a 15 minute moon semi-diameter. Maybe send the results to the list so everyone knows when to stop. Thanks in advance
