That's a "Blue Moon" . . . the second Full Moon in the same CALENDAR month.
The cycle of moon-phases is 29 days, so there has to be a full moon on the 1st or 2nd of the month,
in order to have another one before the end of the month.
December 2009 will have Full Moons on the 2nd and the 31st. That will be the first time in a little over 3 years.

Why does a full moon occur twice in one month?
Actually, the natural cycle of the moon phases was happening first, before humans came along and invented the calendar. So the month is based on the moon. However, any month other than February is longer than the lunar cycle, so occasionally there are two full moons in a month--one on the first or second, and one at the end of the month.
