AR1476 Over Paris by VegaStar2012 on Flickr.
SOLAR ACTIVITY INTENSIFIES: Huge sunspot AR1476 is crackling with M-class solar flares and appears to be on the verge of producing something even stronger. The sunspot's 'beta-gamma-delta' magnetic field harbors energy for X-class flares, the most powerful kind. Earth is entering the line of fire as the sunspot rotates across the face of the sun.
SUNSPOT SUNSET: Sunspot AR1476 is so large, people are noticing it without the aide of a solar telescope. The behemoth appears at sunrise and sunset when the light of the low-hanging sun is occasionally dimmed to human visibility. Alberto Lao sends this picture from Manila, the Phillippines: (above)
