MM#003 Major Flare Watch
by Max Millennium Chief Observer 15 Sep '24

15 Sep '24

Dear Collaborators, The Major Flare Watch target NOAA 13825 was the source of an X4.5 flare at 15:13 UT on September 14 and seven C-class flares. It has been designated as a beta-gamma-delta/D-type configuration with increasing the number of spots significantly. Today the Major Flare Watch campaign continues on this region. Low M-class activities are expected with a chance of a major flare in the next few days. The position of NOAA 13825 on September 15 at 15:30 UT is: S18E39 (-572", -381") 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 was at a moderate level in the past 24 hours. The target region has been designated as NOAA 13825 with a beta-gamma/D-type sunspot group. 13825 was the source of three M-class flares, with the largest one being an M3.0 at 07:26 UT today, and three C-class flares including a C9.4. Today we will continue the Major Flare Watch on this region. It is still emerging some new spots. Low M-class activities are expected with some chance of a major (>M5.0) flare in the next few days. The position of NOAA 13825 on September 14 at 07:30 UT is: S18E59 (-778", -351") 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 continues to be at a high level. There were two major flares, an M6.9 at 09/12/14:31 UT and an M5.3 at 09/13/06:38 UT, produced by the west limb region NOAA 13811 (S13W91, beta-gamma/ D-type). This region was also the source of two low M-class flares and five C-class flares in the period. Considering that 13811 is almost rotating over the west limb, we still keep the Major Flare campaign on the southeast unnumbered region. It produced two low M-class flares, an M1.6 and an M2.1 after yesterday's X1.3 flare. This region has rotated onto the visible disk and seems to have a complex magnetic configuration. Low M-class flares are expected from the two regions as mentioned, with a chance of a >M5 flare in the next 24 hours. The approximate position of the target on September 13 at 07:30 UT is: S17E80 (-890", -280") 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 significantly since the last message. A southeast limb region just produced an X1.3 flare at 09:31 UT today. This limb region also produced an M1.9 flare and five C-class flares during the period. At this time, we are implementing a Major Flare Watch campaign on this limb region which is rotating onto the visible disk. Yesterday's target region NOAA 13814 produced two low M-class flares (M1.8 and M2.0) and retains a beta-gamma- delta/D-type configuration. Also note that NOAA 13811 (S13W82, beta/D-type) was the source of four low M-class flares as well as an M5.0 flare at 23:49 UT yesterday. Low M-class flares are expected from various regions with a good chance of a major flare (>M5) in the next 24-48 hours. The approximate position of the target on September 12 at 09:30 UT is: S16E87 (-920", -280") 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. The largest event in the past 24 hours was an occulted M1.6 flare at 09/10/15:34 UT from the previous limb target region. The present target region NOAA 13814 produced an M1.0 flare at 09/10/23:38 UT and has been designated as a beta-gamma-delta/D-type configuration with increasing the sunspot area and number of spots. Some other regions, such as NOAA 13811 (S12W68, beta/D-type) and 13820 (S18W42, alpha/H-type), produced a few C-class flares during the period. C-class activities are expected with a change of additional low M-class flare in the next 24 hours. The position of NOAA 13814 on September 11 at 07:30 UT is: N16W06 (96", 146") 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. The largest event since the last message was an M3.4 flare at 16:58 UT on September 9 produced by NOAA 13814 that has developed to a beta-gamma/ E-type configuration. 13814 also produced an M1.2 flare at 23:14 UT. Today we will switch the target to this region, which is emerging new magnetic flux in its intermediate portion. Yesterday's target NOAA 13808 plus its nearby regions produced four mid-C-class flares during the period and almost rotated beyond the west limb. Further low M-class flares are expected in the next 24 hours. The position of NOAA 13814 on September 10 at 07:30 UT is: N16E06 (-96", 146") 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. The largest event since the last message was an M1.9 flare at 09/09/05:40 UT, which should be from/near the target region NOAA 13808. 13808 together with 13806 (S08W90, beta/C-type) produced a series of (five) low M-class flares when they were rotating over the west limb. We will watch 13808 (plus 13806) for a further/final 24 hours, whose loops are still visible above the limb. Please note that NOAA 13811 (S10W45) also produced two ~M1 flares during the period and had a beta-gamma/ D-type sunspot group. Further low M-class activities are very likely in the next 24 hours. The position of NOAA 13808 on September 9 at 15:30 UT is: S09W81 (929", -166") 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 remained at a low-to-moderate level since the last message. Yesterday's target region NOAA 13815 (S28E08) retains its beta-gamma configuration but has shown relatively little dynamism in sunspot behaviour during the period. 13815 only produced a C4.4 flare at 17:39 UT yesterday. The largest event in the period was a C7.2 flare at 21:12 UT yesterday produced by NOAA 13808 (S09W65, beta/ C-type). NOAA 13808 and its nearby region NOAA 13806 (S08W74, beta-gamma/D-type) also produced another five C-class flares. The target region shall switch to NOAA 13808, due to its continued flux emergence and the flare history of 13808 and its nearby region NOAA 13806. Further C-class activity is expected, with a chance of low M-class flares in the next 24 hours. The position of NOAA 13808 on 8-Sep-2024 at 11:30 UT is: S09W65 (853",-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 is low-to-moderate. The target region NOAA 13807 has now rotated completely out of view beyond the South West limb. 13807 has only produced a C5.1 flare since the last message. The largest event in the period was a long-duration M1.7 flare produced by NOAA 13813 (S24E10, beta-gamma/F-type) and 13815 (S30E16, beta-gamma/E-type). Today the target region shall switch to NOAA 13815 with a focus towards its leading spots, due to its continued magnetic flux emergence and the complexity of the magnetic field connection between 13815 and the nearby active regions. Please note that NOAA 13806 (S11W60, beta-gamma-delta/D-type) was the source of seven C-class flares in the period. Further C-class activity is likely, with a chance of low M-class flares in the next 24 hours. The position of NOAA 13815 on 7-Sep-2024 at 11:30 UT is: S30E16 (-227",-574") 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. The largest event was a C7.9 flare at 14:03 UT yesterday from NOAA 13806 (S12W44, beta-gamma-delta/E-type). Target region NOAA 13807 (S15W91) has now rotated over the South West limb, with some overlying loops visible above the limb. 13807 remained the most flare-productive region in the period, being the source of over ten C-class flares, including three high C-class flares (two C7.8 and one C7.6). At this time, we are ending the Major Flare Watch but NOAA 13807 shall remain the target region, as it rotates fully out of view beyond the South West limb. Additional C-class activity is expected, with a chance of low M-class flares in the next 24 hours. The position of NOAA 13807 on 6-Sep-2024 at 11:30 UT is: S15W91 (918",-242") 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.
