Want to try? Train your telescope on the dark side of the Moon, which rises around 3 a.m. on Saturday: sky map. Lyrids will be raining down on the northern third of the visible disk. In the eyepiece, watch for fleeting, point-like flashes. Better yet, let a video camera do the watching for you. Brian Cudnik, who coordinates amateur observations of lunar impacts for the Association of Lunar and Planetary Observers, explains how.
SUN SERPENT: Yesterday, astrophotographer Gary Palmer of Los Angeles, California, claims to have spotted the Loch Ness Monster--on the Sun. You decide:
This fluffy solar filament does indeed resemble a sea serpent. In a few days, though, it'll look like something utterly different. The sun's rotation is carrying the filament toward the sun's limb. Soon, it will hang out over the edge, blazing bright against the black space beyond, transforming a dark serpent into a hot glowing ... what? Stay tuned!
