MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Jan '12

31 Jan '12

Dear RHESSI Collaborators, Solar activity remains at a low level. NOAA region 11413 continues in emergence, having increased in spot area, number of spots, and complexity. This region is now classified as a beta/D-type sunspot group with the merging of several leading spots and development of more mature penumbrae. C-class activity is possible in the next 24 hours, with an increasing chance if NOAA 11413 undergoes some flux emergence between the leading and following spots. The position of NOAA 11413 on 31-Jan-2012 at 13:30 UT is: N08E15, ( -243", 232" ) 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.

Dear RHESSI Collaborators, Solar activity has returned to low levels. NOAA region 11413 has recently emerged close to existing NOAA region 11410. NOAA 11413 has undergone relatively rapid emergence and appears to be quite fragmented with a beta magnetic classification. C-class activity is possible, especially if NOAA 11413 continues in emergence. The position of NOAA 11413 on 30-Jan-2012 at 17:30 UT is: N08E28, ( -459", 223" ) 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.

Dear RHESSI Collaborators, The Major Flare Watch comes to an end with the spots of NOAA region 11402 rotating over the North West limb. The limb-passage location of 11402 continues as the target region because the overlying loops of 11402 will remain visible for several hours. C-class activity is possible, with a chance for a footpoint-occulted M-class event. The approximate position of this region on 29-Jan-2012 at 17:30 UT is: N29W90, ( 851", 469" ) 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

28 Jan '12

Dear RHESSI Collaborators, The level of solar activity has decreased as NOAA region 11402 continues rotating over the North Western limb. The Major Flare Watch will remain in effect for one more day as there is still a chance for another >M5 event before NOAA 11402 completely disappears behind the limb. The position of NOAA 11402 on 28-Jan-2012 at 17:30 UT is: N29W90, ( 851", 470" ) 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

27 Jan '12

Dear RHESSI Collaborators, Target region NOAA 11402 on the North Western limb produced an X1.7 flare today beginning at 17:37 UT. At this time we are implementing a Major Flare Watch campaign. There remains a good chance for a >M5 event before the target region rotates completely over the limb. The position of NOAA 11402 on 27-Jan-2012 at 20:30 UT is: N29W83, ( 845", 480" ) 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.

Dear RHESSI Collaborators, NOAA region 11402 continues to be the source of C-class events as it approaches the North West limb, the largest since yesterday's message being a C5.5 flare on 27-Jan-2012 at 06:24 UT. This region is currently classified as a beta/D-type sunspot group, although a higher magnetic complexity may be masked by foreshortening effects close to the limb. Further C-class events are expected in the next 24 hours, with a chance for an M-class event before limb passage. The position of NOAA 11402 on 27-Jan-2012 at 11:00 UT is: N29W78, ( 833", 488" ) 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.

Dear RHESSI Collaborators, NOAA region 11402 has continued to decay, decreasing in area and number of spots. This region has increased in complexity, now classed as a beta-gamma/D-type sunspot group. NOAA 11402 has produced several C-class events since yesterday's message (the largest being a C7.9 flare on 26-Jan-2012 at 01:40 UT). Further C-class activity is likely in the next 24 hours, with a small chance for an M-class event. The position of NOAA 11402 on 26-Jan-2012 at 13:30 UT is: N26W67, ( 808", 458" ) 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.

Dear RHESSI Collaborators, The Major Flare Watch campaign has now finished. NOAA regions 11401 and 11402 have continued to decay, both producing 1 C-class event yesterday. NOAA 11401 remains the more complex of these two regions, maintaining a beta-gamma/E-type sunspot group classification. Further C-class activity is expected, with a small chance for an M-class event. The position of NOAA 11401 on 25-Jan-2012 at 10:30 UT is: N16W58, ( 794", 316" ) 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
by Max Millennium Chief Observer 24 Jan '12

24 Jan '12

Dear RHESSI Collaborators, The Major Flare Watch campaign will continue for today, despite NOAA regions 11402 and 11401 decaying further. Both regions show signs of fragmentation and have decreased in area, while the primary spots of NOAA 11402 have also lost a significant amount of penumbral coverage since the last message. The primary target is NOAA 11402, due to the extremely proton-rich M8.7 flare it produced on 23-Jan-2012 at 03:38 UT. Observers are again encouraged to include the trailing spots of NOAA 11401 in the field-of-view if at all possible. The position of NOAA 11402 on 24-Jan-2012 at 10:00 UT is: N28W41, ( 570", 517" ) 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.

Dear RHESSI Collaborators, NOAA region 11402 produced an M8.7 event on 23-Jan-2012 at 03:38 UT. We are now implementing a Major Flare Watch campaign as there is an increased chance for another >M5 flare in the next 24 hours. Observers are encouraged to include NOAA 11402 and the trailing spots of NOAA 11401 in the field-of-view if at all possible. The position of NOAA 11402 on 23-Jan-2012 at 11:00 UT is: N29W29, ( 412", 541" ) 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.
