Solar activity intensifies – Sunspot AR11476 unleashed a M5.7 Solar Flare – May 10, 2012


Active Region 11471 produced an M1.9 Solar Flare and a weak Halo Coronal Mass Ejection (CME) followed shortly after. This long duration event induced a 10cm Radio Burst or Ten Flare reaching 240 solar flux units.

The incoming CME does have and earth bound component but does not appear to be strong enough to cause a geomagnetic storm. ETA late May 10 to early May 11.

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.

This morning, May 10th around 0418 UT, sunspot 1476 unleashed an impulsive M5.7-class solar flare. This is the 4th M-Class flare in 24 hours from this growing region.

Apparently, the almost-X class explosion did not hurl a significant CME toward Earth. NOAA forecasters estimate a 65% chance of more M-class flares and a 10% chance of X-flares during the next 24 hours.
