Swallow the Moon.

For the first time in 20 years New Year's Eve will be greeted with a blue moon and partial lunar eclipse.

Interestingly enough, a blue moon just indicates the second full moon in a calendar month and not the visible color. But, it should be noted that spotting a real blue moon is possible...just incredibly rare. Atmospheric pollution via sand, smoke or forest fires can cause the visual. One volcanic erruption (Krakatoa) that occurred in 1863 and made the moon look blue for nearly 2 years.

All calendar blue moons are fairly rare (2.72 years in cycle) they are seen as symbolic, 'out of the blue' and are said to be a time to tune in and evaluate ourselves.
