MM#003 Major Flare Watch
Dear RHESSI Collaborators,
After decaying early in the period yesterday, target region NOAA 1515 has increased sunspot area and count as well as magnetic complexity. 1515 is now a large active region with an F-type/beta-gamma-delta sunspot group. There is an area within the central portion that has developed negative polarity spots and plage surrounded by positive polarity spots and plage. 1515 was the source of numerous C-class events and four M-class events since the last message. The largest event was an M5.3 at 07/04/09:54 UT. At this time we are implementing Max Millennium observing plan #003 (Region Likely To Produce A Major Flare). M-class events = or >M5 are likely in the next 24 hour period. There is also a chance of an X-class event in the next 24 to 48 hours.
The position of NOAA 1515 on July 04 at 15:00 UT is: S16W19 (Solar X = 296", Solar Y = -310")
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.
