MM#003 Major Flare Watch

Dear RHESSI Collaborators,

Solar activity is high. Following the previously reported M5 flare on 2011/09/06 01:40 UT, NOAA 11283 was the source of an X2.1 proton (>10MeV) event at 22:20 UT. The event was associated with an Earth directed CME and caused an R3 radio blackout. The region continues to evolve and is now classified as a beta-gamma-delta type. The sunspots within the AR are rapidly converging on each other to the west of the region, most likely driving the high level activity we are getting. The Major Flare Watch campaign will continue as further high level activity is probable with further >=M5 flares possible in the next 24 hours.

The position of NOAA 11283 on 7-Sep-2011 15:30 UT is:

N14W27 ( 417", 125" )
