[AZ-Observing] Re: Seeing Phobos & Deimos

Hi Bill,

I used SkyTools to create finder charts for Mars, Phobos & Deimos at 
15-minute intervals for tonight. Here are the results. All times are MST. 
Position angle and separation are in relation to Mars:

               PHOBOS               DEIMOS
TIME       P.A.    SEP.         P.A.     SEP.
11:00p   275.5     2".3        117.5     42".3
11:15p   293.7     7".7        117.9     45".3
11:30p   296.8   13".0        118.3     48".1
11:45p   298.2   17".8        118.6     50".7
12:00a   299.0   21".9        119.0     53".3
12:15a   299.6   25".1        119.2     55".7
12:30a   300.1   27".3        119.5     57".9
