MM#003 Major Flare Watch
by Max Millennium Chief Observer 31 Jul '11

31 Jul '11

MM#003 Major Flare Watch Dear RHESSI Collaborators, NOAA 1261 has slightly decayed following the M9 event on July 30th but is currently maintaining its beta-gamma-delta magnetic classification. Another major flare is less likely today but an isolated M-class flare is possible in the next 24 hour period. The Major Flare Watch for an event => M5 will continue for at least another day. NOAA 1263, N18E39, also has the potential to produce an isolated M-class event. The position of NOAA 1261 on July 31 at 15:30 UT is: N17E13 (Solar X = -204", Solar Y = 187") 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, Target region, NOAA 1260, decayed significantly and was mostly quiet. NOAA 1261 developed significantly during the past 24 hour period and was very active. 1261 was the source of numerous C-class events and a major very impulsive M9.3 event at 07/30/02:09 UT. 1261 added numerous new spots forming an unusual circular pattern with a beta-gamma-delta magnetic configuration. The target will switch from 1260 to 1261. There is a chance for another =>M5 event. The position of NOAA 1261 on July 30 at 15:30 UT is: N16E24 (Solar X = -370", Solar Y = 178") 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

29 Jul '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1260 has decayed slightly but is still classified as a large E-type/beta-gamma sunspot group with a possible delta configuration. 1260 will continue to produce C-class events and an M-class event is still possible. Two regions located to the east of 1260 (1261, N15E43 and 1263, N18E67) have produced C-class events and could also be the source of an M-class event. The position of NOAA 1260 0n July 29 at 10:30 UT is: N19E11 (Solar X = -171", Solar Y = 222") 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 1260 increased its sunspot area and spot count slightly while maintaining a complex beta-gamma-delta magnetic configuration. It continues to display dynamic bright H-alpha plage but only managed to be the source of C-class events during the past 24 hour period. The largest C-class event was a C5.3 at 07/28/12:12 UT. The Major Flare Watch will be in effect for at least another 24 hour period. An event =, > M5 is still possible. The position of NOAA 1260 on July 28 at 10:30 UT is: N18E24 (Solar X = -366", Solar Y = 213") 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 A Major Flare). Target region, NOAA 1260, was the source of an M1 event earlier today at 16:07 UT. The region has continued to grow since the M1 event adding sunspot area, count and magnetic complexity. It has developed a magnetically complex Beta-gamma-delta configuration. It now has the potential to produce an event = to or > M5.0. The position of NOAA 1260 on July 27 at 20:30 UT is: N20E33 (Solar X = -485", Solar Y = 252") 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 27 Jul '11

27 Jul '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1260 was the source of seven C-class events during the past 24 hour period. The largest was a C3.8 at 07/26/22:41 UT. 1260 added a few new sunspots but remains a D-type/beta sunspot group. 1260 is capable of producing additional C-class events with a slight chance of an isolated M-class event as well. NOAA 1261 at N16E68 is a large D-type/beta group which also has the potential to produce C-class events. The position of NOAA 1260 on July 27 at 10:30 UT is: N20E39 (Solar X = -560", Solar Y = 257") 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

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region, NOAA 1260, was the source of five B-class events and the C1.2 event at 07/26/11:15 UT. NOAA 1261 now rotating onto the visible just east of 1260 produced three B-class events. The largest was a B9.4 at 07/26/03:39 UT. 1260 displayed rapid growth during the past 24 hours. It is currently a D-type/beta sunspot group. 1261 is still too close to the east limb to ascertain its magnetic configuration. Both target region 1260 and 1261 have the potential to produce C-class activity. The position of NOAA 1260 on July 26 at 15:30 UT is: N20E49 (Solar X = -671", Solar Y = 268") 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, The target region, now numbered NOAA 1260, was the source of five B-class events since the last message. The largest was a B7.4 event at 07/24/22:45 UT. 1260 has now completed east limb passage. The region is currently displaying a simple magnetic configuration with a cluster of several small spots. Additional B-class events expected today with a chance of a C-class event as well. The position of NOAA 1260 on July 25 at 15:30 UT is: N20E62 (Solar X = -784", Solar Y = 284") 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

24 Jul '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, The several regions on the visible solar disk are very quiescent. Solar flare activity is expected to continue at a very low level. The target region (most likely the return of old NOAA regions 1243/1246) has mostly rotated over the NE limb. It appears to have just one small leader sunspot. There is weak surging in the trailing portion. No significant solar flare activity is expected during the next 24 hour period. The position of the target region on July 24 at 15:00 UT is: N19E78 (Solar X = -874", Solar Y = 290") 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, The regions on the disk are decaying. The target will switch from NOAA 1254 to a new region located on the east limb. The new region is displaying bright surges in H-alpha. It was the source of two B-class events. The largest was a B5.4 at 07/23/14:49 UT. Additional B-class events expected in the next 24 hour period. There is a slight chance of a C-class event if the region continues in growth phase. The position of the target on July 23 at 14:50 UT is: N19E89 (Solar X = -893", Solar Y = 305") 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.
