Jack, I'm playing with a program called Ephemeris.
The azimuth values I've given were based on magnetic north reference.
The azimuth for San Francisco on June 5 is 101 degrees.
Changing the reading to true north setting I get a reading of 117degrees.
Don't blame me if you can't find the moon, I'm not an astronomer.

Jeff
