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:
