MM#003 Major Flare Watch

Dear RHESSI Collaborators,

The largest x-ray event in the past 24 hours was an impulsive M3.8 at 06/21/09:44 UT produced by NOAA 2367, S17W57. Target region NOAA 2371 was the source of an interesting twin M-class and large flare event. (M2.0 at 06/21/01:42 followed by an M2.7 at 06/21/02:34). The twin event was associated with a full-halo CME. 2371 is maintaining its E-type/beta-gamma-delta sunspot group. An isolated event =/>M5 is possible in the next 24 hour period.

The position of NOAA 2371 on June 21 at 11:00 UT is: N13E10 (Solar X = -160", Solar Y = 186")
