MM#009 Default Target
by Max Millennium Chief Observer 31 Jan '23

31 Jan '23

Dear Collaborators, Solar activity has reached intermediate levels. The largest event since the last message was a C4.8 flare at 10:46 UT on 31-Jan-2023 produced by the limb target region, which was newly numbered as NOAA 13207 and was classified as a beta/C-type sunspot group. This region stays the most productive and has produced 6 C-class flares. Today the target shall still be this region. Please note that a plage region (N20E24) also produced 4 low C-class flares during the period. Further C-class activities are expected in the following 24-hour period. The position of NOAA 13207 on 31-Jan-2023 12:30 UT S13E64 (-854", -175") 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 remains at a low level. The largest event since the last message was a C3.1 flare at 11:52 UT on 30-Jan-2023 produced by an unnumbered limb region (S10E89), which has produced 5 C-class events. Today's target shall switch to this region because of its recent higher frequency of flaring activity. Yesterday's target region NOAA 13200 produced only a C1.3 flare, with signs of decay. Further C-class activities are expected in the following 24-hour period. The approximate position of the target on 30-Jan-2023 12:30 UT S11E88 (-900", -200") 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, Quiescent solar conditions continue despite the presence of several numbered active regions on the visible disk. NOAA 13200 was the source of two ~C1 flares since the last message but has since been downgraded to an alpha spot. It shall continue as the target region for the next 24 hours although no significant increase in activity is expected at this time. The position of NOAA 13200 on 29-Jan-2023 at 08:30 UT is: N21W20, ( 312", 435" ) 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 returned to low levels aside from a few occulted C-class flares from beyond the northwest limb. The region around the southwest limb has also remained quiescent since the last message. NOAA 13200, which is close to the central meridian in the northern hemisphere, was the source of a C3.4 flare at 11:50 UT today and shall be the new target region. It is currently classified as a beta/B-type region and may produce additional isolated low-level events over the next 24 hours. The position of NOAA 13200 on 28-Jan-2023 at 12:30 UT is: N21W08, ( 127", 438" ) 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 decreased since the last message with NOAA 13190 and NOAA 13192 now beyond the western limb. There was a C5.3 flare at 07:00 UT today from an apparent spotless region near the southeast limb, but EUV and coronagraph images show dynamic activity from an approaching region in the same location. The region around the flare shall be the new default target with a possible increase in activity over the coming days. The approximate position of the target region on 27-Jan-2023 at 12:30 UT is: S18E86, ( -924", -293" ) 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 beginning to diminish with NOAA 13190 and NOAA 13192 now beyond the western limb, although NOAA 13192 produced three low M-class flares since the last message. While the magnetic configuration of both regions is now uncertain, the looptops of NOAA 13190 shall continue as the target region for a further 24 hours. Chance remains for an isolated intermediate level event. The position of NOAA 13190 on 26-Jan-2023 at 12:30 UT is: S14W91, ( 944", -236" ) 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 increased since the last message with a series of C-class flares from both NOAA 13190 and NOAA 13192 on the southwest and northwest limbs, respectively. NOAA 13190 was also the source of an M4.7 flare at 09:37 UT today. NOAA 13190 is still classified as a beta-gamma-delta region and shall remain the target region for a further 24 hours. Continued C-level activity likely with chance for an additional isolated M-class flare before the region transits the western limb. The position of NOAA 13190 on 25-Jan-2023 at 12:30 UT is: S14W85, ( 942", -226" ) 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 13190 continues to dominate the solar disk as it approaches the southwest limb and has produced multiple low-to-moderate C-class flares over the past 24 hours. The largest event since the last message was an eruptive C9.5 flare that occurred to the north of NOAA 13192 in the northwest quadrant. NOAA 13190 retains its beta-gamma-delta configuration and shall remain the target region. Further intermediate level activity expected with chance for a low M-class flare before west limb passage. The position of NOAA 13190 on 24-Jan-2023 at 12:30 UT is: S14W64, ( 851", -196" ) 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 intermediate levels with sustained C-level activity from NOAA 13190 as it approaches the western limb. It was also the source of an M1.6 flare at 16:49 UT yesterday. The region retains its beta-gamma-delta configuration and has shown signs of development since the last message. NOAA 13190 shall continue as the target region for the next 24 hours with further high-C/low-M-level activity possible. The position of NOAA 13190 on 23-Jan-2023 at 12:30 UT is: S16W50, ( 719", -212" ) 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. Target NOAA 13190 continued its slow decrease in total sunspot area after the last message, but has now been confirmed as a beta-gamma-delta/E-type sunspot group. Despite this overall decay, the delta spot in NOAA 13190 grew in area during the period and 13190 was the source of the largest magnitude flare - an M1.1 on 22-Jan-2023 at 12:12 UT. More C-class flares are expected in the following 24-hour period, with a good chance for another M-class flare. The position of NOAA 13190 on 22-Jan-2023 at 16:30 UT is: S15W40 , ( 608", -186" ) 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.
