MM#003 Major Flare Watch

Dear RHESSI Collaborators,

NOAA 1520 has decayed slightly losing its magnetic delta configuration but is maintaining its large F-type/beta-gamma sunspot group. It only produced C-class events in the past 24 hour period. NOAA 1521 located just west of 1520 was the source of the largest event (C9.9 at 07/11/08:30 UT). Despite its quiescent behavior, 1520 is capable of producing an M-class event with a slight chance of an M-class event =/>M5 in the next 24 hour period. We'll continue the MFW for at least one more day.

The position of NOAA 1520 on July 11 at 15:00 UT is: S16E10 (Solar X = -158", Solar Y = -323")

See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
