FULL MOON ALERT!
This weekend's full Moon is the biggest and brightest of 2009. It's a "perigee Moon" as much as 50,000 km closer to Earth than other full Moons we'll see later this year. Perigee moonlight shining through icy winter air can produce beautiful halos, coronas, moondogs and other atmospheric optics phenomena. Sample photos are featured on Spaceweather.com.
