MM#003 Major Flare Watch
Dear RHESSI Collaborators,
At this time we are implementing Max Millennium coordinated observing plan #003 (Region Likely To Produce A Major Flare). Target region (now numbered NOAA 1598) was the source of a major impulsive occulted M9 x-ray event at 10/20/18:14 UT. The region is still too close to the limb to ascertain its magnetic configuration. 1598 produced 5 C-class events since the M9 event. The largest was a C7.8 at 10/21/03:07 UT. Another major flare =/>M5 is very possible in the next 24 to 48 hour period. There is also a chance of an X-class event during the same period.
The position of NOAA 1598 on October 21 at 08:45 UT is: S12E80 (Solar X = -929", Solar Y = -215")
