MM#009 Default Target
by Max Millennium Chief Observer 31 Mar '21

31 Mar '21

Dear Collaborators, NOAA 12811 was the source of a B7.4 flare at 19:46 UT yesterday, which preceded the large prominence eruption off the northwest limb. NOAA 12812 is now spotless and continues to decay. It shall remain the target region with no significant change in activity expected over the next 24 hours. Also include NOAA 12811 in your field of view if possible as it rotates towards the western limb. The position of NOAA 12812 on 31-Mar-2021 at 11:30 UT is: N23W43, ( 604", 447" ) 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 has remained at background levels since the last message. NOAA 12812 has remained quiescent and continues to decay. It shall be the target region for another 24 hours although no activity expected at this time. Please also include NOAA 12811 in your field of view if possible. The position of NOAA 12812 on 30-Mar-2021 at 15:30 UT is: N22W31, ( 460", 446" ) 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 very low levels with A-class flares from both NOAA 12811 and 12812 since the last message. NOAA 12812 retains its alpha configuration but continues to decay. It shall remain the target region but also include NOAA 12811 in your field of view if possible. Only A-level activity expected over the next 24 hours. The position of NOAA 12812 on 29-Mar-2021 at 11:30 UT is: N21W19, ( 293", 442" ) 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 largest X-ray event in the past 24 hours was a B1.2 flare (also the only B-class flare) at 03/27/20:34 UT produced by the target region NOAA 12812. 12812 remains its alpha/H-type configuration and now is the only region with sunspots on the visible solar disk. Although NOAA 12811 decays to a plage region, its coronal loops interact with the ones from 12812. If possible, please include both regions in your field of view. Only very low level activities are expected in the next 24 hours. The position of NOAA 12812 on March 28 at 03:30 UT is: N21W01 (15", 449") 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 largest X-ray event in the past 24 hours was a B1.2 flare (also the only B-class flare) produced by NOAA 12811 at 03/26/13:47 UT. 12811 also produced several high A-class flares. It remains its beta/B-type configuration but decays further with losing all of its spots. The target region NOAA 12812 has been almost unchanged, remaining an alpha/H-type sunspot group. If possible, please include both regions in your field of view. Additional B-class activities are likely over the next 24 hours. The position of NOAA 12812 on March 27 at 04:30 UT is: N21E12 (-187", 447") 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 largest event in the past 24 hours was a B8.3 flare at 03/25/15:07 UT produced by NOAA 12812. 12812 also produced another two ~B1 flares. Today the target will switch to NOAA 12812 which remains an alpha/H-type configuration but shows flux emergencies as well as cancellations in its intermediate portion. Yesterday's target region NOAA 12811 has been flare quiet since the last message and remains its beta/B-type sunspot group. If possible, please also include 12811 in your field of view. Further B-class activities are expected in the next 24 hours. The position of NOAA 12812 on March 26 at 04:30 UT is: N21E24 (-366", 441") 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 largest event in the past 24 hours was a B3.0 flare at 03/24/21:52 UT, produced by NOAA 12812 (N21E38). 12812 remains its alpha/H-type configuration. The target region NOAA 12811 only produced two ~A8 flares. 12811 appears to decay and has a beta/B-type sunspot group. If possible, please include both regions in your field of view. Additional B-class activities are likely in the next 24 hours. The position of NOAA 12811 on March 25 at 04:30 UT is: N20E18 (-280", 430") 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 target region NOAA 12811 has produced seven ~B1 flares since the last message, the largest one being a B1.7 at 03/24/04:01 UT. 12811 now has a beta/C-type configuration, increasing in its sunspot area and number of spots. The region near 12811 has been designated as NOAA 12812 (N21E50) with an alpha/H-type classification. If possible, please also include 12812 in your field of view. More B-class activities are expected over the next 24 hours. The position of NOAA 12811 on March 24 at 04:30 UT is: N19E30 (-456", 407") 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 target region NOAA 12811 has produced three ~B1 flares since the last message, the largest one being a B1.8 at 03/22/20:33 UT. 12811 remains its beta/B-type configuration, with slightly increasing in its sunspot area. Near 12811 there is another region (N20E64, unnumbered yet) showing some spots. If possible, please also include this region in your field of view. Low B-class activities are expected in the next 24 hours. The position of the target NOAA 12811 on March 23 at 12:30 UT is: N20E40 (-582", 411") 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 largest X-ray event in the past 24 hours was a B5.6 flare produced by NOAA 12810 (N18W04) at 03/22/01:10 UT. 12810 was the target region in previous days but now has decayed to a plage region. The new target region near the northeast limb has been designated as NOAA 12811 today and has a beta/ B-type configuration. 12811 produced three ~B1 flares in the past 24 hours. Further B-class activities are expected over the next 24 hours. The position of the target NOAA 12811 on March 22 at 04:30 UT is: N21E55 (-737", 405") 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.
