MM#003 Major Flare Watch
by Max Millennium Chief Observer 28 Feb '23

28 Feb '23

Dear Collaborators, Solar activity has been at a low level since the last message, with low C-class flares from NOAA 13234. However, the region has increased in size and complexity, and is now classified as a beta-gamma-delta region due to mixed polarities within the trailing sunspot. This portion of the active region also appears to be coalescing and rotating which may introduce significant sheering along the polarity inversion line. As such we are implementing a Major Flare Watch campaign at this time due to the increased possibility of a M5 flare or greater over the next 24-48 hours. The position of NOAA 13234 on 28-Feb-2023 at 12:30 UT is: N25W29, ( 426", 503" ) 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 Target
by Max Millennium Chief Observer 27 Feb '23

27 Feb '23

Dear Collaborators, Solar conditions have remained at the low C-level since the M6.4 flare on 25-Feb-2023, with NOAA 13229 now approaching the western limb. NOAA 13234 remains unchanged in terms of size and complexity, maintaining a beta-delta configuration with a sunspot area >500uh, and shall continue as the default target region. Further C-level activity likely with chance for an isolated low M-class flare over the next 24 hours. The position of NOAA 13234 on 27-Feb-2023 at 08:30 UT is: N25W14, ( 213", 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.

MM#009 Default Target
by Max Millennium Chief Observer 26 Feb '23

26 Feb '23

Dear Collaborators, Solar activity is at a moderate-to-high level. Target region NOAA 13234 remained stable in sunspot area and number of sunspots since the last message, continuing to be classed as a beta-delta/E-type sunspot group. This region only produced one C-class flare in the period (a C3.2 on 26-Feb-2023 at 07:55 UT). The largest magnitude flare was an M6.3 from NOAA 13229 on 25-Feb-2023 at 18:40 UT that was accompanied by a CME. At this time the Major Flare Watch comes to an end, but NOAA 13234 will remain the target because it still has a delta configuration and NOAA 13229 has shown signs of decay following its M6.3 and CME. C-class activity is expected over the next 24 hours, with a chance for more M-class flares. The position of NOAA 13234 on 26-Feb-2023 at 18:30 UT is: N25W05 , ( 76", 517" ) 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. Target region NOAA 13234 was stable in terms of spot area and number of spots since the last message, remaining classified as a beta-delta/E-type sunspot group. NOAA 13234 again produced C-class activity in the period, but the largest magnitude flare was an M3.7 from NOAA 13229 on 24-Feb-2023 at 20:03 UT. The Major Flare Watch will remain on NOAA 13234 for a possibly final 24 hours because it retains a reasonable delta spot. M-class flares are possible in the following 24-hour period. The position of NOAA 13234 on 25-Feb-2023 at 15:00 UT is: N25E11 , ( -167", 516" ) 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 moderate level. Target NOAA 13234 grew further in terms of spot area and number of spots since the last message, and increased in complexity to be classed as a beta-delta/E-type sunspot group. NOAA 13234 continued to produce C-class events in the period. Although the rate and magnitude of flaring has decreased, the Major Flare Watch continues on NOAA 13234 for another 24 hours. Additional M-class activity is possible over the next 24 hours. The position of NOAA 13234 on 24-Feb-2023 at 16:30 UT is: N25E24 , ( -360", 508" ) 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. Target NOAA 13234 has grown in terms of spot area and number of spots since the last message and has increased in complexity to be classified as a beta-gamma/E-type sunspot group. The largest magnitude flare in the period was an M1.5 on 23-Feb-2023 at 06:11 UT, produced by a new sunspot group that is emerging slightly ahead of target region NOAA 13234 (but has not been numbered by NOAA yet). NOAA 13234 has continued to be flare-productive since the last message, being the source of multiple C-class flares and an M1.0 on 23-Feb-2023 at 08:32 UT. The Major Flare Watch will continue with NOAA 13234 as the target for at least another 24 hours. Further M-class flares are probable in the following 24-hour period, with a chance for a low X-class flare. The position of NOAA 13234 on 23-Feb-2023 at 15:00 UT is: N25E39 , ( -554", 493" ) 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 moderate-to-high level. Target NOAA 13234 has been stable in terms of spot area and number of spots, and remained classified as a beta/D-type sunspot group. NOAA 13234 has continued to be the most flare-productive region on disk being the source of three M-class flares since the last message, including the largest magnitude flare in the period - an M5.0 on 21-Feb-2023 at 19:57 UT. The Major Flare Watch continues with NOAA 13234 as the target. More M-class activity is expected over the next 24 hours, with a chance for a low X-class flare. The position of NOAA 13234 on 22-Feb-2023 at 17:00 UT is: N24E51 , ( -688", 461" ) 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

21 Feb '23

Dear Collaborators, The level of solar activity is moderate. The target region has rotated onto the visible disk and is now numbered as NOAA 13234. This region has been designated as a beta/D-type sunspot group, but this may be affected by foreshortening due to its proximity to the limb. This region has continued to produce multiple high C-class flares since the last message, as well as the largest flare of the period - an M4.7 on 21-Feb-2023 at 11:14 UT. The MM#003 Major Flare Watch will continue on NOAA 13234. Further M-class activity is probable in the following 24-hour period. The position of NOAA 13234 on 21-Feb-2023 at 18:30 UT is: N24E66 , ( -811", 436" ) 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 moderate level. Target region NOAA 13229 grew slightly since the last message and was reclassified as a beta-delta/E-type sunspot group. This region has produced four C-class flares in the period, the largest being a C5.5 flare on 20-Feb-2023 at 17:37 UT. A new spot region is in the process of rotating over the North East limb and has already produced four C-class flares and the largest magnitude flare of the period - a foot-point occulted M4.4 on 20-Feb-2023 at 14:47 UT (therefore of actually larger peak magnitude). The MM#003 Major Flare Watch will remain in effect, but the target switches to this currently unnumbered region at the North East limb. More C-class activity is expected over the next 24 hours, with a good chance for M-class flares. The approximate position of this region on 20-Feb-2023 at 19:00 UT is: N26E90 , ( -871", 422" ) 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 13229 was reclassified as a beta-delta/D-type sunspot group since the last message. This region only produced a C2.7 flare on 19-Feb-2023 at 14:50 UT. The MM#003 Major Flare Watch will remain in effect on NOAA 13229 for a further 24 hours. Further C-class flares are expected in the following 24-hour period, with a chance for an M-class flare. The position of NOAA 13229 on 19-Feb-2023 at 17:00 UT is: N26E36 , ( -513", 510" ) 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.
