MM#009 Default Target
by Max Millennium Chief Observer 20 Jan '22

20 Jan '22

Dear Collaborators, Solar activity has been at a low level since yesterday's M5.5 flare from the target region NOAA 12929. The largest event during the period was a B9.6 flare at 01/20/23:49 UT produced by 12929. 12929 remains its beta/D-type configuration and it is rotating over the west limb. B-class activities are expected and C-class flares are possible in the next 24 hours. The position of NOAA 12929 on January 21 at 04:30 UT is: N08W91 (964", 133") 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 been at a moderate level. An M5.5 flare was produced by the target region NOAA 12929 at 01/20/05:41 UT. 12929 also produced three low C-class flares during the period. This region still has a beta/D-type sunspot group and continues decaying when it is rotating to the west limb. If possible, please also include NOAA 12930 (N21W75, with a beta/D-type configuration) in your field of view. B- and C-class activities are expected with a slight chance for an additional M-class flare in the next 24 hours. The position of NOAA 12929 on January 20 at 04:30 UT is: N07W74 (931", 141") 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 was at a moderate level. An M1.5 flare was produced by the target region NOAA 12929 at 01/18/17:01 UT. In addition, a C5.7 flare was produced by the neighboring region NOAA 12930 (N21W62, with a beta/C-type sunspot group). The target 12929 has decayed to a beta/D-type configuration. If possible, please also include 12930 in your field of view. B- and C-class activities are expected with a slight chance for another low M-class flare in the next 24 hours. The position of NOAA 12929 on January 19 at 04:30 UT is: N07W61 (847", 159") 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 12929 has been classified as a beta-gamma/ D-type configuration. It continues showing mixed polarities in its northern portion. The neighboring region NOAA 12930 (N21W48) produced two C-class flares (C2.8 and C2.7 around 13:50 UT and 15:00 UT respectively) in the past 24 hours. 12930 remains its beta/D-type configuration while increasing in its sunspot area and number of spots. If possible, please also include 12930 in your field of view. Additional C-class events are likely in the next 24 hours. The position of NOAA 12929 on January 18 at 04:30 UT is: N07W47 (709", 174") 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 12929 remains a beta/D-type configuration. It shows mixed polarities in its north portion. If possible, please also include NOAA 12930 (N20W31) in your field of view, which has a beta/D-type sunspot group as well. B- and C-class activities are expected in the next 24 hours. The position of NOAA 12929 on January 17 at 04:30 UT is: N08W33 (527", 202") 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-to-moderate. The target region was confirmed as being numbered as NOAA 12932 with a beta/C-type sunspot group classification. NOAA 12932 was again the source of two C-class flares since the last message, but the largest flare of the period was produced by growing region NOAA 12929 (a C2.6 on 16-Jan-2022 at 20:04 UT) that appears to have developed a delta spot configuration in addition to its beta/D-type sunspot group classification. 12929 becomes the new target because of its flux emergence over the past 24 hours. C-class activity is expected in the following 24 hours. The position of NOAA 12929 on 16-Jan-2022 at 21:30 UT is: N08W32 , ( 512", 203" ) 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-to-moderate level. The target region that was rotating over the North East limb displays a beta magnetic class, and is expected to be numbered as NOAA 12932 at the start of the next UT day. This region continued producing several C-class flares since the last message, which included the largest flare of the period - a C4.2 flare on 15-Jan-2022 at 08:33 UT. This region will continue as the target, with C-class flares expected over the next 24 hours and a chance for another low M-class flare. The approximate position of this region on 15-Jan-2022 at 20:00 UT is: N32E63 , ( -738", 546" ) 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 moderate. The target region beyond the North East limb has begun rotating onto the visible disk with signs of some leading polarity spots that are extremely foreshortened, so the region is not capable of being classified yet. This region continued producing several C-class flares over the past 24 hours as well as a footpoint-occulted M1.8 flare on 14-Jan-2022 at 01:47 UT. This limb region will remain as the target, with C-class activity expected in the following 24-hour period and a chance for a low-to-mid M-class flare. The approximate position of this region on 14-Jan-2022 at 20:00 UT is: N31E90 , ( -836", 500" ) 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 small flux region that began emerging spots yesterday has now been designated as NOAA 12928 and is classed as a beta/D-type sunspot group, but has remained flare quiet. The target region over the North East limb is now close to rotating onto the visible disk. This has continued to be the most flare-active region with producing 2 C-class flares since the last message, a C1.8 and a C2.9 on 13-Jan-2022 at 01:51 UT and 11:18 UT, respectively. This limb-crossing location continues as the target for the next 24 hours, with further C-class activity probable. The approximate position of this region on 13-Jan-2022 at 20:30 UT is: N32E90 , ( -827", 515" ) 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 very low. Target region NOAA 12926 was confirmed as a beta/C-type sunspot group but has remained flare quiet since the last message. Another small flux region is in the process of emerging spots in the southern hemisphere close to central meridian, but has not yet produced any flaring activity. The most flare-active location has been a limb-occulted region over the North East limb that was the source of two B-class flares (an impulsive B7.2 on 12-Jan-2022 at 04:13 UT and a CME-associated long-duration B9.1 on 12-Jan-2022 at 04:36 UT). This limb-crossing location will become the new target with additional B-class activity expected in the next 24 hours and a chance for C-class flaring. The approximate position of this region on 12-Jan-2022 at 23:00 UT is: N32E90 , ( -827", 515" ) 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.
