MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Sep '11

30 Sep '11

Dear RHESSI Collaborators, NOAA 11302 has decayed significantly over the past 24 hours and has remained relatively quiescent. NOAA 11305, on the other hand, has increased in both size and complexity and is now classified as a beta-gamma region. The region was the source of a C7.7 flare today at 03:37 UT and shall be the new target region. Further C-level activity possible with chance for an isolated low M-class if the region continues to develop. The position of NOAA 11305 on 30-Sep-2011 at 09:30 UT is: N13E10, ( -162", 106" ) 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, Solar background flux remains steady below the C1 level. The target region NOAA 11302 maintains its large sunspot area with some mixed polarity within the leader spot, and was the source of a C9.3 and an M1.1 flare at 12:26 and 13:24 UT, respectively, on 28-Sep-2011. Further C-level events possible with chance of an isolated M-class flare. The position of NOAA 11302 on 29-Sep-2011 at 09:30 UT is: N13W09, ( 151", 105" ) 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. At this time we are ending the Major Flare Watch campaign. NOAA 11302 retains its large sunspot area but has lost a lot of its complexity. Only C-class flares have been produced in the past 24 hours. NOAA 11302 shall continue to be the target region with further C-level events likely as it crosses the central meridian. The position of NOAA 11302 on 28-Sep-2011 at 09:30 UT is: N13E02, ( -38", 103" ) 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 27 Sep '11

27 Sep '11

Dear RHESSI Collaborators, Solar activity has begun to decrease with NOAA 11302 now downgraded to a beta-gamma region. The largest event since the last message was an M2.6 flare at 14:37 UT on 26-Sep-2011. We shall continue the Major Flare Watch for a further 24 hours as the region still has the potential to produce another >M5 flare. The position of NOAA 11302 on 27-Sep-2011 at 09:30 UT is: N13E17, ( -273", 107" ) 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 26 Sep '11

26 Sep '11

Dear RHESSI Collaborators, NOAA 11302 retains its beta-gamma-delta configuration and has produced 3 M-class flares since the last message. The Major Flare Watch will continue with NOAA 11302 as the target region. Good chance for further M-level activity with the possibility of an isolated X-class flare. The position of NOAA 11302 on 26-Sep-2011 at 09:30 UT is: N12E30, ( -469", 100" ) 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.

25 Sep '11

Dear RHESSI Collaborators, The Major Flare Watch will continue with target region NOAA 11302. This region was the source of an X1.9 event on 24-Sep-2011 at 09:21 UT and has produced 7 M-class events since. NOAA 11302 has increased in area and spots, and is now classified as an F-type/beta-gamma-delta sunspot group. Further M-class activity is probable, with a chance for an X-class event. The position of NOAA 11302 on 25-Sep-2011 at 13:00 UT is: N12E40, ( -601", 111" ) 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.

24 Sep '11

Dear RHESSI Collaborators, Solar activity remains high, with both large E-type/beta-gamma classified sunspot groups (NOAA 11295 and 11302) producing M-class events in the last 24 hours. The MFW target will continue to be NOAA 11302 as it rotates further onto the solar disk, with a chance for a >M5 event if NOAA 11302 undergoes growth or flux emergence. The position of NOAA 11302 on 24-Sep-2011 at 10:00 UT is: N13E53, ( -751", 146" ) 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.

23 Sep '11

Dear RHESSI Collaborators, The target region, now designated NOAA 11302, has been classified as a beta-gamma region and has a prominent leader spot. The region has continued to produce high C-level events since the X-class flare yesterday. Chance remains for an additional major flare within the next 24 hours. The position of NOAA 11302 on 23-Sep-2011 at 09:30 UT is: N11E68, ( -871", 138" ) 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 target region on the eastern limb produced an X1.4 flare beginning at 10:29 UT today. At this time we are implementing a Major Flare Watch campaign. Good chance for an additional >M5 flare within the next 24 hours. The position of target region on 22-Sep-2011 at 11:30 at UT is: N10E88, ( -941", 162" ) 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 22 Sep '11

22 Sep '11

Dear RHESSI Collaborators, The unnumbered active region encroaching over the eastern limb was the source of an M1.8 flare at 12:04 UT on 21-Sep-2011, as well as several C-class flares, and shall be the new target region. The magnetic configuration is uncertain at this time but additional C-class flares are likely, with increased chance of another M-level event. The approximate position of the target region on 22-Sep-2011 at 09:30 UT is: N15E88, ( -922", 241" ) 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.
