MM#003 Major Flare Watch
by Max Millennium Chief Observer 11 Aug '24

11 Aug '24

Dear Collaborators, Solar activity has decreased to a moderate level since the last message. Target region 13780 (S10W16) was the most flare-productive region in the period, being the source of eight mid-to-high flares and three low M-class flares, including the largest magnitude in the period - an M1.6 flare at 05:23 UT today. 13780 gained a delta spot and is now classified as a beta-gamma-delta/F-type sunspot group, with an area of 1200 MSH. The Major Flare Watch shall remain in effect with NOAA 13780. Additionally, NOAA 13782 (N03E21, beta/E-type) produced an M1.2 flare yesterday. Further low M-class activity is expected, with a chance of >M5 flares in the next 24-48 hours. The position of NOAA 13780 on 11-Aug-2024 at 11:30 UT is: S10W16 (257",-265") 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 high level since the last message. The largest event was an M5.3 flare at 02:14 UT today, produced by the target region NOAA 13780 (S12W04). This region also produced another three ~M1 flares plus four mid-to-high C-class flares in the period. 13780 has been reclassified as a beta-gamma /F-type sunspot group with an area of 1280 MSH. We shall continue the Major Flare Watch on this region today. Additionally, NOAA 13777 (S09W40, beta-gamma/E-type) and NOAA 13784 (N15E54, beta/C-type) were also the sources of three M-class flares in the period, including an M4.6 flare from NOAA 13777 yesterday. Further M-class activity is expected, with a chance for additional >M5 flares from various regions in the next 24-48 hours. The position of NOAA 13780 on 10-Aug-2024 at 11:30 UT is: S12W04 (64",-299") 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 level since the last message. The largest event was an X1.3 flare at 19:01 UT yesterday, produced by NOAA 13777 (S09W26). This region remains classified as a beta-gamma-delta configuration but is becoming much more fragmented. Target region NOAA 13780 (S12E10) produced four ~M1 flares and three mid-level C-class flares in the period. 13780 retains a beta-gamma-delta/F-type configuration with a slight increase in sunspot area (now 1250 uh). This region now appears some signs of spot spilt in its leading portion. Today, the Major Flare Watch shall remain in effect with NOAA 13780 due to its overall size, magnetic complexity, and further evolution. M-class activity is expected, with a good chance of >M5 flares from various regions in the next 24-48 hours. The position of NOAA 13780 on 9-Aug-2024 at 11:30 UT is: S12E10 (-161",-297") 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 to a moderate-to-high level. The largest event in the period was an M5.0 flare at 18:31 UT yesterday produced by NOAA 13777 (S09W13, beta-gamma-delta/E-type). 13777 was also the source of another three low M-class flares in the period. Additionally, a South East limb region (S11E88) and NOAA 13781 (N13E29, beta-delta/D-type) also produced three low M-class flares. Target region 13780 (S09E20) produced only six C-class flares in the period, with a slight decrease in sunspot area (now 1110 uh) and an increase in number of spots. 13780 has remained a beta-gamma-delta configuration and high current helicity since the last message. 13780 continues to undergo a significant flux emergence across the entire active region. Today, the Major Flare Watch shall remain in effect with NOAA 13780, with a focus on its leading spots. Further M-class activity is expected, with a good chance of >M5 flares from various regions in the following 24-48 hours. The position of NOAA 13780 on 8-Aug-2024 at 11:30 UT is: S09E20 (-320",-244") 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 since the last message. Target region NOAA 13780 (S13E37) produced only two mid-level C-class flares during the period. However, 13780 retains its beta- gamma-delta/F-type configuration with an increasing sunspot area (now 1220 uh) and number of spots. Considering that 13780 remains a high current helicity and continues to undergo a significant flux emergence in its leading portion, today we will continue the Major Flare Watch on this region. Please note that the largest event in the period was an M4.5 flare at 13:30 UT today produced by NOAA 13774 (S07W17, beta-gamma/E-type). 13774 was also the source of an M1.8 flare and three mid-to-high C-class flares in the period. Additionally, NOAA 13781 (N13E46, beta-gamma/D-type) produced an M1.1 flare as well. M-class activities are expected with a chance of >M5 flares from various regions in the next 24-48 hours. The position of NOAA 13780 on 7-Aug-2024 at 11:30 UT is: S13E37 (-556",-292") 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 very high level since the last message. Target region NOAA 13780 (S13E51) produced an X1.1 flare at 15:18 UT yesterday. 13780 has been designated as a beta-gamma -delta/F-type configuration with a sunspot area of 930 uh. Today, the Major Flare Watch shall remain in effect with NOAA 13780 due to its magnetic complexity, high current helicity, and continued flux emergence. Please note that limb region NOAA 13767 produced the largest event in the period - an X1.7 flare at 13:24 UT yesterday, but this region has now rotated over the South West limb. M-class activities are expected, with a good chance of >M5 flares from various regions in the next 24-48 hours. The position of NOAA 13780 on 6-Aug-2024 at 11:30 UT is: S13E51 (-717",-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 remains at a high level. Yesterday's limb target region has been quiescent since the last message. The largest event in the period was an M6.1 flare at 05:13 UT today from the leading portion of NOAA 13780 (S10E64, beta/D-type). 13780 was the most flare-productive region in the period with generating another three low M-class plus four C-class flares. Today, the Major Flare Watch shall switch to this region due to its continued flux emergence, especially in its leading portion. Additionally, NOAA 13767 (S09W85) also produced an M1.7 flare in the period. Further M-class activity is expected, with a chance for additional >M5 flares from various regions in the following 24-48 hours. The position of NOAA 13780 on 5-Aug-2024 at 11:30 UT is: S10E64 (-838",-207") 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 since the last message. Yesterday's target region NOAA 13765 was flare-quiet but its nearby region NOAA 13766 (S07W90) was the source of three ~M1 flares and four mid-to-high C-class flares in the period. A northeastern limb region (N12E88) produced four M-class flares, including an M5.5 at 19:17 UT yesterday, and two mid-to-high C-class flares in the period. Today, the Major Flare Watch shall switch to this limb region, although NOAA 13775 (N17E11, beta-gamma/D-type) produced the largest event during the period - an M7.3 flare at 18:29 UT yesterday. Further M-class activity is expected, with a chance for >M5 flares from various regions in the next 24-48 hours. The approximate position of the target on 4-Aug-2024 at 11:30 UT is: N12E88 (-924",192") 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 diminished since the last message. Yesterday's target NOAA 13768 produced an M1.5 flare and six mid-to-high C-class flares in the period, but is now completely out of view. The largest event in the period was an M1.9 flare at 07:11 UT today, produced by NOAA 13765 (S11W68, beta-gamma-delta/E-type). 13765 was also the source of two mid-to-high C-class flares in the period. Today, the Major Flare Watch shall switch to NOAA 13765 due to its magnetic complexity, continued flux emergence, and the complexity of the magnetic field connection between it and the nearby active regions. Please note that a northeastern limb region (N12E88) and some other active regions (NOAA 13775, 13766, 13777 and 13770) were also the source of M-class flares in the period. Further M-class activity is expected, with a chance for >M5 flares from various regions in the next 24-48 hours. The position of NOAA 13765 on 3-Aug-2024 at 11:30 UT is: S11W68 (861",-215") 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 high level since the last message. Target region NOAA 13768 has now rotated over the South West limb, with some overlying loops visible above the limb. This region produced two ~M1 flares and the largest magnitude flare in the period - an M7.4 at 04:23 UT today. The Major Flare Watch shall remain in effect with NOAA 13768 for a final 24 hours, as it rotates fully out of view beyond the South West limb. Additionally, NOAA 13774 (beta- gamma/E-type) produced five ~M1 flares during the period. Some other active regions (NOAA 13765, 13772, 13766, 13764, and 13773) also produced M-class flares. Further M-class activity is expected, with a good chance for additional >M5 flares from various regions in the next 24-48 hours. The position of NOAA 13768 on 2-Aug-2024 at 11:30 UT is: S16W91 (908",-257") 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.
