MM#009 Default Target
by Max Millennium Chief Observer 11 Mar '22

11 Mar '22

Dear Collaborators, Solar activity is at a low level. Target region NOAA 12965 has been stable since the last message and remains classified as a beta/E-type sunspot group. NOAA 12962 produced a long-duration C2.8 flare on 10-Mar-2022 at 18:15 UT that was the largest in the period. 12965 was also flare-productive, being the source of three low C-class flares. More C-class flares are expected in the following 24-hour period, with a small chance for a low M-class flare. The position of NOAA 12965 on 11-Mar-2022 at 20:30 UT is: N23E36 , ( -523", 466" ) 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 Collaborators, The level of solar activity is low. Target region NOAA 12965 has now rotated fully onto the visible disk and it has been re-designated as a beta/E-type sunspot group. Most of the spotted regions on disk have remained flare quiet, with NOAA 12965 producing the largest flare of the period in the form of a B7.7 on 10-Mar-2022 at 09:18 UT. C-class activity is expected over the next 24 hours, with a small chance for a low M-class flare. The position of NOAA 12965 on 10-Mar-2022 at 20:00 UT is: N23E49 , ( -674", 448" ) 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 Collaborators, Solar activity is at a low level. The target region has now been numbered as NOAA 12965 and is designated as a beta/D-type sunspot group. This region appears to have some small intermediate spots, but it remains too close to the limb to accurately assign magnetic classification based on these. NOAA 12965 has continued producing B-class flares since the last message, as well as two C1.0 flares (the largest of the period) on 9-Mar-2022 at 07:49 and 12:42 UT. More C-class activity is expected in the following 24-hour period, with a chance for a low M-class flare. The position of NOAA 12965 on 9-Mar-2022 at 21:30 UT is: N22E63 , ( -802", 410" ) 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 Collaborators, The level of solar activity is low. Target region NOAA 12962 remained stable since the last message, continuing to be classified as a beta/ C-type sunspot group. The spotted regions on the visible disk have all been unremarkable in terms of flaring activity since the last message. A new spotted region currently rotating over the North East limb has been the source of several C-class events, including the largest flare of the period - a C2.0 on 8-Mar-2022 at 03:01 UT. These would have all been foot-point occulted events, so potentially significantly higher in peak flux if they had occurred on disk. Further C-class activity is expected over the next 24 hours, with a chance for a low M-class flare. The approximate position of this region on 8-Mar-2022 at 22:00 UT is: N24E90 , ( -882", 390" ) 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 Collaborators, Solar activity is at a low level. Target region NOAA 12960 has been stable and flare-quiet since the last message, remaining classified as a beta/D-type sunspot group. The target switches to NOAA 12962, a beta magnetic active region that developed penumbrae on its spots since the last message. NOAA 12962 had produced multiple low C-class flares before yesterday's message and, although only producing high B-class flares since then, it remains one of the more flare-active of the spotted regions on disk. C-class activity is probable in the following 24-hour period. The position of NOAA 12962 on 7-Mar-2022 at 19:00 UT is: N26E33 , ( -472", 514" ) 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 Collaborators, There has been a series of low C-class flares from a newly-emerged region in the northeast quadrant (NOAA 12962) since the last message. NOAA 12960 in the southeast quadrant has remained quiescent but continues to develop with new flux emergence within its core. It shall continue as the target region for a further 24 hours with low-level activity possible. The position of NOAA 12960 on 6-Mar-2022 at 16:30 UT is: S20E35, ( -522", -234" ) 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 Collaborators, Solar activity continues at the B-level. NOAA 12957 has remained quiescent since the last message, and has reverted back to a beta region. The region in the southeast quadrant has been designated as NOAA 12960, and is classified as a beta/D-type region. It continues to produce low-level activity, and has developed significantly over the past 24 hours. It shall be the default target region once again with further low-to-intermediate level activity possible. The position of NOAA 12960 on 5-Mar-2022 at 12:30 UT is: S21E50, ( -693", -271" ) 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 Collaborators, Solar activity continues at a low level, with B- and C-class flares emanating from NOAA 12960 in the southeast quadrant. NOAA 12957 retains its beta-gamma configuration, and has shown signs of further flux emergence in its trailing portion, but has remained quiescent. It shall continue as the target region for a further 24 hours, with C-level activity possible. The position of NOAA 12957 on 4-Mar-2022 at 12:30 UT is: S15W15, ( 242", -135" ) 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 Collaborators, There was an M2.0 flare from a spotless NOAA 12958 at 17:31 UT yesterday, while NOAA 12957 has developed into a beta-gamma/E-type region, but has remained quiescent. Both regions appear to be connected by a transequatorial loop system. The unnumbered region near the southeast limb continued to produce B- and C-level activity since the last message, but has shown signs of decay. At this time we will revert the target region back to NOAA 12957, which may become flare productive if it continues to develop. The position of NOAA 12957 on 3-Mar-2022 at 12:30 UT is: S15W00, ( 0", -131" ) 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 Collaborators, NOAA 12957 has continued to develop since the last message, and was the source of a C3.0 flare at 09:12 UT today. However, the default target shall switch to a region currently along the southeast limb that has been the source of several B-class flares, as well as a C1.9 flare at 04:05 UT today. The magnetic configuration of the region is uncertain at this time but increased activity is likely over the next 24 hours as it rotates into view. The approximate position of the target region on 2-Mar-2022 at 08:30 UT is: S21E87, ( -902", -337" ) 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.
