Three M-class flares from Region 1476 on May 9, 2012

Three M-class flares from Region 1476 on May 9, 2012

Region 1476, now poised just to the east of center on the solar disk, produced an impulsive R1(Minor) Radio Blackout at 12:32 UTC (8:32 EDT) - M4.7 solar flare peaking at 12:32 UT then an M1.8 peaking at 14:08 UTC on May 09, 2012. The region is quite prominent, although just one-third in area of the large regions of the Halloween Storms in 2003, and exhibits a slight degree of magnetic complexity.

It will be in direct alignment with earth in a few days, so CME's then would be likely to spawn geomagnetic activity.

Increased activity is looming! We might see more today.

A pair of solar eruptions from May 7th hurled coronal masss ejections (CMEs) toward Earth. Forecast tracks prepared by analysts at the Goddard Space Weather Lab suggested that clouds would arrive in succession on May 9th at 13:40 UT and May 10th at 07:54 UT (+/- 7 hours). The double impact could spark moderate geomagnetic storms. High-latitude sky watchers should be alert for auroras.

Update: At about 21:03 UTC third M-class solar flare erupted from the same region, this time M4.1.

This page will be updated when new data becomes available.
