THUNDER MOON: Picture this: The sound of distant thunder draws you to the window. Lightning zig-zags across the night sky, storm clouds part, and a brilliant beam of moonlight lances through the curtain, spotlighting the observer.
Tonight, this could happen to you. There's a full Moon, the "Thunder Moon," named after the electrical storms of summer. David Hoffmann photographed the waxing Thunder Moon last night in Ashland, Oregon:
The Moon reaches maximum illuminattion on Tuesday, July 3rd, at 18:52 UT. Look for it rising in the east at sunset, and enjoy the thunder moonlight.
