There's a "Supermoon" tonight ... last night really, but we missed it.

This full Moon will appear to be up to 14% larger and 30% brighter than most other full moons during the year.

The reason for this phenomenon being that this month the Moon becomes full on its closest approach to Earth on May 5, 2012.

Here's a nice NASA video explaining the "Supermoon" phenomenon, a term coined by our good friend Richard Nolle.

It should still be pretty good again tonight if you have clear skies.
