Although the full moon that occurred Tuesday, December 1, 2009, looked like an ordinary full moon, it was actually a bit extraordinary—a blue moon.
For a blue moon to occur, the first of the full moons must appear at or near the beginning of the month so that the second will fall within the same month:
First December full moon: December 1, 2009

Second December full moon: December 30, 2009
- Stay tuned……………….
