MM#003 Major Flare Watch
by Max Millennium Chief Observer 31 Jul '24

31 Jul '24

Dear Collaborators, Solar activity has returned to a high level since the last message. The largest event was an M9.4 flare at 19:25 UT on July 30, produced by the southeast region NOAA 13772 (S25E52, beta/D-type). This region also produced an M6.0 flare peaking at 13:05 UT, happening just now. Yesterday's target region, NOAA 13764 (S03W40, beta/D-type), was the source of an M1.9 flare and two high C-class flares. Today, the Major Flare Watch will switch to 13772. Additionally, some other active regions located on the southern visible solar disk were the source of M-class flares, including an unnumbered region near the east limb (S07E88, M4.8) and some western active regions: NOAA 13768 (S16W64, beta-gamma-delta/E-type, M7.7), 13773 (S06W50, beta /C-type, M2.0), and 13766 (S07W32, beta-gamma/E-type, M1.5). 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 13772 on 31-Jul-2024 at 11:30 UT is: S25E52 (-676",-451") 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-intermediate level. The largest event since the last message was an M6.4 flare at 19:40 UT from an unnumbered region near the South East limb (S25E70). This region also produced an M4.3 flare at 14:04 UT yesterday. The target region NOAA 13764 has decayed slightly in sunspot area and number of spots and was confirmed as an alpha/H-type configuration, while NOAA 13766 (S07W18) emerged new spots to be classified as a beta-gamma-delta/E-type region. This close pair of NOAA regions only produced two M1 flares in the period. Today the Major Flare Watch region will continue as NOAA 13764 due to its past >M5 activities and proximity to NOAA 13766. Further low-M activities are expected with a good chance for additional >M5 flares from various regions in the following 24 hours. The position of NOAA 13764 at 11:30 UT on 30-Jul-2024 is: S03W26 (415", -133") 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 still been high since the last message. The largest event was an X1.5 flare at 02:33 UT today from the target region between 13764 and NOAA 13766. 13764 has been classified as a beta/C-type sunspot group and 13766 (S07W03) has retained a beta/D-type configuration over the past 24 hours. Their intermediate portion with mixed polarities appears to be away from 13766 and thus closer to 13764. Today the Major Flare Watch will switch to 13764 (with NOAA 13766 in the field of view). In addition, NOAA 13762 (beta-gamma-delta/F-type, S11W49) also produced an M7.8 flare at 10:27 UT yesterday and an M8.7 flare at 12:47 UT today. Further low-M activities are expected with a good chance for additional >M5 flares in the following 24 hours. The position of NOAA 13764 at 11:30 UT on 29-Jul-2024 is: S03W13 (213", -139") 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 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.
