Observation 09/16/10

At about 9:30, I went outside at home and saw the waxing gibbous moon in the South at an azimuth of about 60 degrees. I went outside again at about 10:30 and the moon had moved west and the azimuth decreased (due mainly to the Earth's rotation). Finally, I looked shortly after 11:00 and sure enough, the moon was even lower and farther west. This was the first time I had ever observed the Moon's apparent movement for myself, which was fascinating!
