MM#003 Major Flare Watch
by Max Millennium Chief Observer 28 Feb '11

28 Feb '11

MM#003 Major Flare Watch Dear RHESSI Collaborators, NOAA 1164 was the source of numerous C-class events and an isolated M1.1 event at 02/28/12:45 UT. As mentioned yesterday, the magnetic delta configuration has decayed but 1164 is maintaining a complex beta-gamma classification with an E-W magnetic inversion line in the leading polarity portion. C-class activity expected with another M-class event possible and a slight chance of an isolated event equal to or greater than M5. The position of NOAA 1164 on February 28 at 12:30 UT is: N27E39 (Solar X = -544", Solar Y = 521") 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.

MM#003 Major Flare Watch Dear RHESSI Collaborators, NOAA 1164 continues to be the source of low-level events. The largest was a C4.2 at 02/27/03:55 UT. The regions magnetic configuration is a complex beta-gamma but the large leading penumbra has split losing its delta configuration. The changes of a major flare have decreased somewhat but 1164 is still capable of producing an isolated M-class event. The position of NOAA 1164 on February 27 at 12:30 UT is: N28E53 (Solar X = -684", Solar Y = 516") 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.

MM#003 Major Flare Watch Dear RHESSI Collaborators, The target region (now numbered NOAA 1164) has a complex magnetic delta configuration. 1164 is displaying point brightening and continuous surges in H-alpha images. It has produced numerous B- and C-class events associated with the point brightening but hasn't produced any high level activity since the M3.5 (behind the east limb) event on the 24th. 1164 has the potential to produce an M5 event or larger in the next few days. The position of NOAA 1164 on February 26 at 15:40 UT is: N28E67 (Solar X = -788", Solar Y = 339") 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.

MM#003 Major Flare Watch Dear RHESSI Collaborators, A large leader sunspot is visible on the NE limb. This new region was the likely source of the M3.5 event yesterday at 07:31 UT. This region is located northeast of newly numbered NOAA 1163. If possible, include 1163 within your F-O-V. An event equal to M5 or larger is possible in the next few days. The approximate position of the target on February 25 at 11:00 UT is: N20E85 (Solar X = -908", Solar Y = 339") 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.

MM#003 Major Flare Watch Dear RHESSI Collaborators, At this time we are implementing Max Millennium Coordinated Observing Plan #003 (Region Likely To Produce Major Flares). An active region located just behind the NE limb was the source of an M3.5 event at 02/24/07:31 UT. The region is too close to the east limb to ascertain its magnetic configuration. A major flare (M5 class event or greater) is possible. The position of the target on February 24 at 07:30 UT is: N14E87 (Solar X = -940", Solar Y = 239") 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.

MM#009 Default HESSI Target
by Max Millennium Chief Observer 23 Feb '11

23 Feb '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, Both NOAA regions 1161 and 1162 continue in slow decay phase. 1161 produced a C1.2 event at 02/23/12:23 UT. Another C-class event is possible today. The position of NOAA 1161 on February 23 at 12:30 UT is: N11W63 (Solar X = 849", Solar Y = 237") 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.

MM#009 Default HESSI Target

22 Feb '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1158, located beyond the west limb, produced another C-class event since the last message. The target will switch to NOAA 1161. 1161 and 1162 are slowly decaying with simple magnetic configurations but an isolated C-class event is still possible. The position of NOAA 1161 on February 22 at 12:30 UT is: N11W49 (Solar X 720", Solar Y = 261") 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.

21 Feb '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region, NOAA 1158, produced a few C-class events in the past 24 hours. The largest was a C7.8 at 02/21/10:12 UT. The trailing portion of this large region is on the west limb. We'll watch1158 again today. Further interesting limb events possible. The likely target tomorrow will be NOAA regions 1161/1162. 1161/1162 have been the source of low-level C-class activity. The position of NOAA 1158 on February 21 at 12:30 UT is: S21W91 (Solar X = 905", Solar Y = -346") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, No M-class events since the last message but NOAA region 1158 and dual regions 1161/1162 have the potential to produce an isolated M-class event. Target region 1158 is now rotating over the west limb. C-class activity possible with the chance of an isolated M-class event in the next 24 hours. The position of NOAA 1158 on February 20 at 12:30 UT is: S19W85 (Solar X = 914", Solar Y = -303") 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.
