MM#003 Major Flare Watch
by Max Millennium Chief Observer 28 Jul '24

28 Jul '24

Dear Collaborators, Solar activity has reached a high level. The largest events since the last message were two consecutive high-M flares from two adjacent active regions, NOAA 13766 and 13764. The two flares include an M7.9 at 01:39 UT and an M9.9 at 01:53 UT today eruptive with dimming and coronal waves. 13766 has developed to be a beta/D-type configuration and 13764 (S05E04) has been classified as an alpha/H-type sunspot group, both of which are surrounded by the other three active regions (NOAA 13763, 13765, and 13767). At this time, we are implementing a Major Flare Watch on NOAA 13766 (with NOAA 13764 in the field of view). Yesterday’s target region NOAA 13762 (beta-gamma-delta/F-type, S12W34) was a source of three low-to-mid M-class flares. Further low-M activities are expected with a good chance for another>M5 flare in the following 24-48 hours. The position of NOAA 13766 at 07:30 UT on 28-Jul-2024 is: S07E15 (-243", -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 increased to a mid-M level since the last message. The largest event, an M4.2 flare at 02:21 UT today, came from NOAA 13766 (beta/C-type, S07E21) which has displayed separation of its main spots and emerged new spots in the period. The target region NOAA 13762 produced an M3.1 flare at 05:12 UT plus an M2.0 flare at 10:16 UT today. 13762 has also emerged new spots in its leading portion, with a beta-gamma-delta/F-type magnetic configuration. Today 13762 should remain with the target region due to its higher magnetic complexity. Further C-class activities are expected with a good chance for more low-to-mid M-class flares from the two regions in the following 24 hours. The position of NOAA 13762 at 11:30 UT on 27-Jul-2024 is: S12W27 (420", -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 returned to a moderate level due to two low-M flares, including an M1.7 flare at 04:30 UT today from NOAA 13761 (beta-gamma/D-type, S10W77) and an M1.3 flare at 15:27 UT yesterday from NOAA 13751 (beta-gamma/D-type, S08W91). The target region NOAA 13762 only produced several C-class flares in the period, with the largest being a C5.8 flare at 11:20 UT today. This region has increased in spot maturity to display penumbra on its leading spots, changing to a beta-gamma-delta/F-type sunspot group. 13762 will continue to be the target region for a further 24 hours. Further C-class activities are expected with a chance for additional low-M flares from various regions in the next 24 hours. The position of NOAA 13762 at 11:30 UT on 26-Jul-2024 is: S12W11 (176", -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.

Dear Collaborators, Solar activity has been at a moderate-to-low level in the past 24 hours. The largest event, an M2.9 flare at 17:07 UT yesterday, came from NOAA 13751 (beta-gamma/D-type, S08W77). The target region NOAA 13762 also produced two high-C flares, including a C8.4 at 00:24 UT and a C9.1 at 01:54 UT today). It has remained a beta-gamma-delta/E-type sunspot group and continued to grow slightly in the number of sunspots and spot area. Further C-class activities are expected with another low-M flare possible in the following 24 hours. The position of NOAA 13762 at 11:30 UT on 25-Jul-2024 is: S12E03 (-48", -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.

Dear Collaborators, The level of solar activity remains moderate due to an M3.6 flare at 07:28 UT today from NOAA 13751 (beta-gamma-delta/E-type, S08W63). This region continues to reduce in sunspot area and number as it transits towards the South West limb. The target region NOAA 13762 retains a beta-gamma-delta/E-type sunspot group, with a significant emergence of negative magnetic fluxes in its intermediate portion. 13762 should continue as the target region. Further C-class activities are expected with an additional low-M flare possible in the next 24 hours. The position of NOAA 13762 at 11:30 UT on 24-Jul-2024 is: S12E17 (-271", -276") 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 low-to-moderate level in the last 24 hours. The largest event since the last message was an M2.5 flare at 13:49 UT today from NOAA 13764 (alpha/H-type, S11E88). NOAA 13762 has increased its magnetic complexity to be classified as a beta-gamma-delta/E-type configuration and produced a C9.0 flare at 15:20 UT yesterday. Yesterday’s target NOAA 13751 (beta-gamma-delta/E-type, S08W49) showed magnetic signs of decay and only produced a C4.5 flare. Today we shall end the Major Flare Watch campaign, and the default target shall switch to NOAA 13762 due to its increased configuration and prior flaring history. Further C-class flares are expected with a chance for additional low-M flares in the next 24 hours. The position of NOAA 13762 at 14:30 UT on 23-Jul-2024 is: S13E29 (-450", -283") 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 slightly in the past 24 hours. NOAA 13762 (beta/D-type, S13E44) produced three consecutive low-M flares, with the largest being an M4.0 at 03:55 UT today. NOAA 13744 (beta/D-type, N15W90) also was a source of three low-M flares, the largest of which was an M3.2 flare at 23:21 UT yesterday. The target region NOAA 13751 retains its beta-gamma-delta/E-type configuration but only has produced several C-class flares. The MM#003 Major Flare Watch continues with NOAA 13751 as the target for a final 24 hours. Further C-class flares are expected with a chance for a mid-to-high M-class flare from various regions over the following 24 hours. The position of NOAA 13751 at 13:00 UT on 22-Jul-2024 is: S08W35 (538", -198") 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 continued to be moderate. The target region NOAA 13751 was a source of an M1.5 flare at 08:28 UT today. 13751 has undergone slight decay since the last message but has remained a beta-gamma-delta/E-type sunspot group. The MM#003 Major Flare Watch continues for a further 24 hours with NOAA 13751 as the target. Please also note that NOAA 13744 (beta/C-type, N15W77) produced two M1 flares as it rotated toward the North West limb, with the largest event in the period (an M1.6 at 18:36 UT yesterday). Continued low-M activity is possible with a chance of a >M5 flare in the next 24-hour period. The position of NOAA 13751 at 11:30 UT on 21-Jul-2024 is: S09W22 (350", -222") 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 moderate level. The target region NOAA 13751 produced two largest magnitude flares, including an M2.0 at 17:53 UT yesterday and an M1.8 at 07:10 UT today. This region retains its beta-gamma-delta/E-type magnetic configuration and has increased in sunspot area and counts. Today NOAA 13751 shall continue as the Major Flare Watch region. Besides, NOAA 13758 (beta/B-type, S07W75) also produced an M1.0 flare at 22:44 UT yesterday. Additional low-M activity is very likely with a chance of a >M5 flare in the following days. The position of NOAA 13751 at 11:30 UT on 20-Jul-2024 is: S08W06 (98", -210") 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 a moderate level. NOAA 13753 (beta/C-type, N15W69) showed signs of decay and produced an M3.2 flare at 08:13 UT today as it rotated to the North West limb. NOAA 13751 has now developed into a beta-gamma-delta/E-type region and has been the most magnetically complex one on the disk, with an area of 400 MSH. 13751 shows signs of mixed polarity within its leading and intermediate portions. Today the Major Flare Watch region will switch back to NOAA 13751. Yesterday’s target NOAA 13738 has rotated out of Earth-view. More low-M activity is probable with a chance of a >M5 flare in the coming days. The position of NOAA 13751 at 11:30 UT on 19-Jul-2024 is: S08E07 (-114", -208") 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.
