BIG NEW SUNSPOT: New sunspot 1476 is large and crackling with impulsive M-class solar flares. Because of the active region's location near the east limb, the eruptions are not geoeffective, although this could change in the days ahead as the sunspot turns toward Earth. Solar flare alerts: text, phone.
LIVE METEOR RADAR: NASA's all-sky fireball network captured another haul of bright eta Aquarid meteors last night--ten fireballs in all. This suggests that the shower is still active, and might even be peaking, on May 6th. Tune into Space Weather Radio for live echoes from these bits of Halley's Comet as they fly over the US Air Force Space Surveilance Radar in Texas.
SUPER MOON: Last night's full Moon was a "super moon," as much as 14% bigger and 30% brighter than other full moons of 2012. The phenomenon, also known as a perigee moon, is caused by the elliptical shape of the Moon's orbit around Earth. Big, nearby moons like this come along about once a year; they are harmless, beautiful, and, seen from certain angles, very romantic:
VegaStar Carpentier of Paris, France, took the picture on May 5th.
The moonlight was so intense in Veszprem, Hungary, "the birds started singing because they thought it was morning," reports Monika Landy-Gyebnar. "I went out at 2 AM in almost daylight conditions. The landscape was visible in full color, the sky was vivid blue and only the brightest stars were visible. The perigee Moon lit the world with its full brightness."
