Moonrise August 31, 2012
The second full moon of that August

Canon Rebel

The term "Blue Moon" has several different meanings. One is the second full moon in a calendar month.

The lunar cycle, full moon to full moon, is about 29.5 days so these occur only every 2-3 years. Since the defined beginning and ending of a
month depend on the local time, a Blue Moon may occur in a given month for one time zone but for another time zone.
