MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1654 has increased its magnetic complexity during the past
24 hours. 1654 produced 13 C-class events and two M-class events
since the last message. The M-class events were an M1.2
at 01/11/09:11 UT and a long-duration M1.0 at 01/11/15:06 UT.
1654 is a large F-type/beta-gamma-delta region. The leading
portion of the region has a large amount of opposite polarity plage
surrounding the leader sunspot. At this time we are implementing
Max Millennium coordinated observing plan #003 (Region Likely
To Produce A Major Flare). An isolated M-class event =>M5 is
possible in the next 24 hour period.
The position of NOAA 1654 on January 11 at 14:00 UT is:
