MM#003 Major Flare Watch
by Max Millennium Chief Observer 13 Nov '24

13 Nov '24

Dear Collaborators, Solar activity has increased to an intermediate level since the last message. The largest event was an M1.0 flare at 00:11 UT today (11/13), produced by the target region NOAA 13889 (S09W07). This region retains a beta- gamma-delta magnetic configuration and produced another eight C-class flares in the period. The Major Flare Watch will remain effective with NOAA 13889 for the next 24 hours, due to its magnetic complexity and increasing activity. Please note that NOAA 13879, which recently rotated beyond the west limb, produced a C8.3 flare at 12:36 UT yesterday (11/12). Additional C-class activity is expected, with a chance of an isolated >M5 flare in the next 24-48 hours. The position of NOAA 13889 on 13-Nov-2024 at 08:30 UT is: S09W07 (117",-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, Solar activity has decreased to a low level since the last message. The target region NOAA 13889 (S10E06) remains the most flare- productive region during the period. It retains a beta-gamma-delta sunspot group and was the source of eight C-class flares, including the largest magnitude in the period - a C4.4 at 14:19 UT yesterday (11/11). The Major Flare Watch will remain effective with NOAA 13889 for a further 24 hours, due to its magnetic complexity and prior flaring history. Please note that NOAA 13884 (S07W47, beta/ C-type) also produced a C4.3 flare at 07:40 UT today. Further C-class activities are expected, with a slight chance of an isolated >M5 flare in the next 24 hours. The position of NOAA 13889 on 12-Nov-2024 at 08:30 UT is: S10E06 (-100",-220") 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 to a high-to-moderate level since the last message. The largest event in the period was an M4.9 flare at 20:09 UT yesterday (11/10) produced by the target region NOAA 13889 (S10E21). This region retains a beta-gamma-delta magnetic configuration with a slight increase in the spot area (now 480 μH). 13889 also produced an M1.4 flare at 05:36 UT today and several C-class flares during the period. Today the Major Flare Watch shall remain with NOAA 13889, due to its magnetic complexity, high current helicity, and continued flux emergence. M-class activities are expected, with a chance of an isolated >M5 flare in the next 24-48 hours. The position of NOAA 13889 on 11-Nov-2024 at 12:30 UT is: S10E21 (-343",-219") 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 a high level, due to an M9.4 flare at 11:51 UT today produced by NOAA 13889. 13889 retains a beta-gamma-delta/E-type sunspot group and has increased in the spot area to 450 μh. Today the Major Flare Watch shall switch to NOAA 13889 because of its high complexity, and large size, and return to M-class flaring. Yesterday’s target NOAA 13883 (S06W42, beta-gamma-delta/F-type) was flare quiet over the period. Additional low-M activities are probable, with a chance for another >M5 flare in the next 24 hours. The position of NOAA 13889 on 10-Nov-2024 at 12:30 UT is: S10E31 (-493", -216") 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 to an intermediate level. The largest event since the last message was a C7.4 flare at 23:54 UT yesterday produced by NOAA 13889 (S10E42). It also was a source of eight C-class flares and the most productive region. 13889 has been classified as a beta-gamma-delta/E-type sunspot group. The target NOAA 13883 appears to be decaying and was confirmed as a beta-delta/F-type sunspot group. It only produced four C-class flares with the largest being a C7.3 flare at 12:15 UT today. Today the Major Flare Watch will be extended for the final 24 hours with NOAA 13883. More C-class activities are expected, with a slight chance for an isolated major flare in the following 24 hours. The position of NOAA 13883 on 9-Nov-2024 at 16:30 UT is: S06W31 (497", -151") 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 still at a moderate level since the last message. The largest event was an M2.3 flare at 14:49 UT yesterday produced by the target region NOAA 13883. This region also produced an M1.5 at 02:53 UT today plus six C-class flares. 13883 has been classified as a beta-gamma-delta/F-type magnetic configuration, with some consolidation of its main spots. Today the Major Flare Watch shall continue as NOAA 13883. Yesterday’s limb region has been numbered as NOAA 13889 (S10E59, beta-delta/E-type), only a source of several ~C5 flares over the period. Additional low-M activities are probable, with an isolated above-M5 flare likely in the coming 24 hours. The position of NOAA 13883 on 8-Nov-2024 at 12:30 UT is: S07W14 (233", -176") 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 high-to-moderate level since the last message. The target region NOAA 13883 produced the largest event - an X2.3 flare at 13:24 UT yesterday. This region retains its beta-gamma-delta/E-type magnetic configuration and has grown marginally in the sunspot area, with the continuous shearing motion of its intermediate spots. Today the Major Flare Watch shall remain with NOAA 13883. Note that a productive region near the South East limb (S08E79, unnumbered yet) also produced an M5.3 flare at 14:27 UT yesterday. Further C-class and low-M activities are expected, with a good chance for >M5 flares from the two regions in the following 24 hours. The position of NOAA 13883 on 7-Nov-2024 at 12:30 UT is: S06W00 (0", -163") 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 high level in the past 24 hours. The largest event since the last message was an M5.9 flare at 08:48 UT today produced by an unnumbered region (N17W65). This region between NOAA 13878 and the North West limb was newly emerged in the period. The target region NOAA 13883 has experienced notable shearing and additional flux emergence and has been classified as a beta-gamma-delta/E-type sunspot group. It was the most complex region on the disk. Today the Major Flare Watch will continue as NOAA 13883. Further C-class and low-M activities are expected, with a good chance for additional >M5 flares in the next 24 hours. The position of NOAA 13883 on 6-Nov-2024 at 12:30 UT is: S06E14 (-233", -163") 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 has increased due to an M5.6 flare at 15:26 UT yesterday from the target region NOAA 13883. 13883 has continued to grow in spot maturity to display an irregular distribution on both polarities and well-developed penumbrae on its following portion, changing it to a gamma-delta/E-type magnetic configuration. Therefore, we are initiating a Major Flare Watch campaign at this time, with an increased probability of another >M5 flare in the coming 24-48 hours. The position of NOAA 13883 on 5-Nov-2024 at 08:30 UT is: S06E32 (-511", -157") 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 04 Nov '24

04 Nov '24

Dear Collaborators, Solar activity continues at a moderate level. The largest event since the last message was an M3.8 flare at 01:05 UT today from NOAA 13883. This region also produced six low-M flares. It has developed into a beta-gamma-delta/E-type sunspot group with polarity mixing and separation of its main spots. Today we shall end the Major Flare Watch campaign, and the default target shall switch to NOAA 13883 due to its current flaring level and dynamic sunspot behavior. Yesterday’s target NOAA 13878 decreased in the sunspot area and only produced an M1.4 flare at 04:31 UT. Further C-class activities are expected, with more low-M flare possible in the next 24 hours. The position of NOAA 13883 on 4-Nov-2024 at 12:30 UT is: S06E44 (-670", -149") 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.
