Go outside and look up this Saturday, Jan. 10! A perigee full moon — 14 percent wider and 30 percent brighter than lesser moons — will be illuminating the night. Perigee full moons come around once or twice a year. There was one like it in December, and 2009’s is already on its way, giving those that didn’t see the first a second chance. If you’re in a particularly snowy area this weekend, the reflection will create enough light to read a newspaper. Even if you’re not “with snow,” perigee is the point where the moon gets closest to the Earth in orbit, so this weekend’s full moon will be big and bright just about anywhere– as long as it’s not too cloudy.
