MM#009 Default Target
by Max Millennium Chief Observer 30 Nov '23

30 Nov '23

Dear Collaborators, Solar activity has diminished since the last message. The largest event in the period was a C3.8 flare at 14:27 UT yesterday from the target region NOAA 13500, which also produced another five low C-class flares in the period. 13500 retains its beta-gamma magnetic configuration and has increased in terms of spot area and number of spots. NOAA 13500 will remain as the target region due to its continued flux emergence, although we are ending the Major Flare Watch at this time. Further C-class activity is likely, with a slight chance of M-class flares. The position of NOAA 13500 on 30-Nov-2023 at 08:30 UT is: S18W23, (362",-317") 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

Dear Collaborators, Solar activity is at a high level. The largest event since the last message is an M9.8 flare at 19:35 UT yesterday from the target region NOAA 13500. 13500 retains its beta-gamma magnetic configuration and continues to undergo flux emergence. It shall remain the target region. At this time, we are implementing the Major Flare Watch campaign. Further C-class activities are expected over the following 24-hour period, with a chance for another above M5 flare. The position of NOAA 13500 on 29-Nov-2023 at 08:30 UT is: S19W10, (160",-336") 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 slightly increased since the last message. The largest event in the period was a C6.7 flare at 18:40 UT yesterday, attributed to the target region NOAA 13500. However, another flare at the same time, caused by a filament eruption located to the west of NOAA 13503, also contributed to the soft X-ray flux. NOAA 13500 was downgraded to a beta-gamma magnetic configuration but is still experiencing the emergence of new magnetic fluxes. It shall remain as the default target region for an additional 24 hours, with further C-class flares likely. The position of NOAA 13500 on 28-Nov-2023 at 12:30 UT is: 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 continued at a low level since the last message. A number of low C-class flares were produced and ten of them were from the northwest quadrant, including the largest in the period - a C3.4 at 08:03 UT today from NOAA 13490. NOAA 13500 retains its beta-gamma-delta configuration but has decreased slightly in spot area and number of spots. This region has only produced three C-class flares since the last message. At this time we are ending the Major Flare Watch campaign. NOAA 13500 shall continue as the target region for a further 24 hours due to its magnetic complexity and flux emergence in its leading portion. Further C-class activities are expected from various regions with a slight chance of a low M-class flare in the next 24-hour period. The position of NOAA 13500 on 27-Nov-2023 at 12:30 UT is: S19E16, (-254",-339") 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

Dear Collaborators, Solar activity has continued at a reduced level since the last message. Several C-class flares were produced, the largest being C4.4 at 13:16 UT yesterday attributed to NOAA 13503. NOAA 13500 retains its beta-gamma-delta configuration and has increased to approximately 560 μh in area. This region has produced only three C-class flares since the last message. However, the Major Flare Watch will be extended for a further 24 hours, with a slight chance of > M5 activity. The position of NOAA 13500 on 26-Nov-2023 at 12:30 UT is: S18E29, (-449", -322") 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 slightly reduced since the last message. A small number of C-class flares were produced, the largest being a C5.6 from NOAA 13495 at 22:02 UT yesterday. NOAA 13500 retains its beta-gamma-delta configuration and now has an approximate area of 530 μh. The Major Flare Watch will continue as this region still shows potential to produce >M5 activity over the next 24-48 hours. The position of NOAA 13500 on 25-Nov-2023 at 12:30 UT is: S19E43, (-628", -336") 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 continued at an intermediate level since the last message. Two M1 flares were produced over the last 24 hours from NOAA 13490 and NOAA 13499. A new beta-gamma-delta region in the southeast quadrant has been numbered as NOAA 13500. This region has an approximate area of 520 μh and has shown signs of potential rotational shearing and additional flux emergence. At this time, we are implementing a Major Flare Watch campaign with NOAA 13500 as the new target region, with a chance for a >M5 flare over the next 24-48 hours. The position of NOAA 13500 on 24-Nov-2023 at 12:30 UT is: S18E58, (-785", -315") 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 continued at an intermediate level since the last message. Several C-class flares were produced over the last 24 hours. An M1.5 flare was attributed to NOAA 13494. However, this appears to be a combination of two events, where the observed flux is dominated by an eruption from a region over the northeast limb. NOAA 13492 continues to grow in both area and sunspot number while retaining its beta-gamma configuration. NOAA 13492 will continue to be the target region for a further 24 hours, with a chance for further C-class flares. The position of NOAA 13492 on 23-Nov-2023 at 12:30 UT is: N18E29, (-449", 274") 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 continued at an intermediate level since the last message. Several C-class flares were produced over the last 24 hours, the largest being a C8.9 from NOAA 13492 at 06:17 UT today. NOAA 13492 retains its beta-gamma configuration and the number of sunspots attributed to this region has increased. NOAA 13492 will continue to be the target region, with further C-class activity expected. The position of NOAA 13492 on 22-Nov-2023 at 12:30 UT is: N18E43, (-631", 277") 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 continued at an intermediate level since the last message. Several C-class flares were produced over the last 24 hours, the largest being a C6.7 from NOAA 13489 at 03:38 UT today. Multiple active regions are now visible on the disk, particularly in the northeast quadrant, the largest being NOAA 13492. NOAA 13492 is currently classified as a beta-gamma type region and will be the default target region. Further C-class activity is likely over the next 24 hours. The position of NOAA 13492 on 21-Nov-2023 at 12:30 UT is: N18E57, (-776", 281") 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.
