M-FLARES: New sunspot AR1504 is crackling with impulsive M-class solar flares, including two on June 9th (1132 UT and 1650 UT) and one on June 10th (0645 UT). So far none of the blasts have been Earth directed.
NASA's Solar Dynamics Observatory photographed the extreme UV flash from an M2-class flare this morning:
NOAA forecasters estimate a 45% chance of more M-flares today. Geoeffective eruptions are possible in the days ahead as AR1504 turns toward Earth. Stay tuned.. Solar flare alerts: text, voice.
