MM#009 Default Target
by Max Millennium Chief Observer 23 Nov '24

23 Nov '24

Dear Collaborators, Solar activity has returned to a moderate level. The largest event since the last message was an M1.6 flare at 15:42 UT yesterday (11/22), produced by the target region NOAA 13905 (S09E59). This region has increased in magnetic complexity to a beta-gamma type and produced another four C-class flares in the period. NOAA 13905 will remain the target today, as it is showing mixed polarities in the intermediate portion. Please note that NOAA 13906 (S16E68, beta/D-type), located near the target region, produced an M1.1 flare and three C-class flares in the period. If possible, please also include 13906 in your field of view. Further low M-class flares are expected in the next 24-hour period. The position of NOAA 13905 on 23-Nov-2024 at 08:30 UT is: S09E59 (-824",-167") 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 is at a moderate-to-low level. The largest event since the last message was a C9.1 flare at 03:23 UT today (11/22), produced by the target region 13901 (S07E14). It remains classified as a beta-gamma /D-type sunspot group and produced another two C-class flares in the period. However, its spot activity appears relatively stable. Please note that a limb region NOAA 13905 (S09E71, beta/D-type) also produced two mid-C-class flares in the period and now exhibits relatively high current helicity. Today, the target region shall switch to NOAA 13905. Further C-class activity is expected, with a chance of low M-class flares in the next 24 hours. The position of NOAA 13905 on 22-Nov-2024 at 12:30 UT is: S09E71 (-908",-162") 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. The largest event since the last message was an M1.2 flare at 19:11 UT yesterday (11/20), produced by NOAA 13889, which has completely rotated over the west limb. The regions NOAA 13892 and 13897, which have also rotated over the west limb, were the sources of several C-class flares. The target region NOAA 13901 (S07E28) retains a beta-gamma magnetic configuration and produced three C-class flares in the period. At this time, we are ending the Major Flare Watch, but NOAA 13901 shall remain the target region as it is emerging new magnetic flux in its trailing portion. Further C-class activity is expected, with a chance of low M-class flares in the next 24 hours. The position of NOAA 13901 on 21-Nov-2024 at 12:30 UT is: S07E28 (-454",-149") 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
by Max Millennium Chief Observer 20 Nov '24

20 Nov '24

Dear Collaborators, Solar activity is now at a moderate-to-low level. The largest event since the last message was a C9.0 flare at 16:59 UT yesterday (11/19), produced by the target region NOAA 13901 (S08E44). This region retains a beta-gamma magnetic configuration and produced a C8.0 flare plus another four C-class flares in the period. The Major Flare Watch shall remain in effect with NOAA 13901 for a further 24 hours due to a slight chance of an >M5 flare. Additionally, regions near the southeast limb, e.g. NOAA 13897 (S10W82), have remained active and produced several C-class flares during the period. The position of NOAA 13901 on 20-Nov-2024 at 12:30 UT is: S08E44 (-669",-161") 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 largest event since the last message was an M2.0 flare at 18:45 UT yesterday (11/18), produced by the target region, which has been numbered as NOAA 13901 (S07E56, beta-gamma/D-type). This region also produced an M1.8 flare and three C-class flares in the period. The Major Flare Watch shall remain effective with NOAA 13901 over the next 24 hours due to continued flux emergence. Additionally, regions near the southeast limb, NOAA 13889 (S09W88), 13897 (S12W69), and 13895 (S03W71), also produced two M1.1 flares and several C-class flares during the period. Further M-class flares are expected, with a chance of >M5 flares from the limb regions in the next 24-48 hours. The position of NOAA 13901 on 19-Nov-2024 at 12:30 UT is: S07E56 (-800",-140") 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.

18 Nov '24

Dear Collaborators, Solar activity has increased to a moderate level since the last message. The largest event in the period was an M3.7 flare at 12:42 UT today (11/18), produced by the limb target region (S06E73, still unnumbered). This limb region was also the source of another four M-class flares (M1.0, M1.7, M1.3, and M2.5) and several C-class flares in the period. At this time, we are implementing the Major Flare Watch campaign with the southeast limb region. Additionally, two regions near the southwest limb, NOAA 13897 (S12W54) and 13889 (S09W78), also produced several C-class flares and an M1.6 flare in the period. Further M-class flares are expected, with a chance of >M5 flares from the limb regions in the next 24-48 hours. The approximate position of the target on 18-Nov-2024 at 12:30 UT is: S06E73, ( -924", -113" ) 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 decreased to a low level since the last message. The largest event in the period was a C5.4 flare at 10:38 UT today (11/17), produced by a southeast limb region (S09E89), which also produced another six C-class flares in the period. The target region shall switch to this limb region. Yesterday's target NOAA 13892 (S11W50, alpha/A-type) produced three low C-class flares in the period, while the nearby region NOAA 13889 (S09W64, beta-gamma -delta/F-type) produced a C4.5 flare during the decay phase of the C5.4 flare. Further C-class activity is expected, with a chance of low M-class flares in the following 24-48 hours. The approximate position of the target on 17-Nov-2024 at 12:30 UT is: S09E89, ( -958", -152" ) 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. Yesterday's target region NOAA 13889 (S09W50) only produced a low C-class flare during the period, although it retains a beta- gamma-delta/F-type configuration. The largest event in the period was an M1.6 flare at 01:26 UT today (11/16), produced by NOAA 13892 (S11W36, beta/B-type), which was also the source of another six C-class flares. Today, the target region shall switch to this region. Additionally, NOAA 13893 (S19E27, beta/C-type) also produced an M1.0 flare in the period (12:05 UT, 11/15). Further low M-class activities are expected in the next 24 hours. The position of NOAA 13892 on 16-Nov-2024 at 12:30 UT is: S11W36 (561",-221") 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 an intermediate level. The largest event since the last message was an M1.1 flare at 01:38 UT today (11/15), produced by NOAA 13893 (S19E43, beta/C-type). The target region NOAA 13889 (S09W34, beta-gamma-delta/F-type) and its nearby regions, NOAA 13892 (S11W20) and 13891 (S15W47), produced five low C-class flares in the period. At this time, we are ending the Major Flare Watch, but NOAA 13889 shall remain the target region, due to its magnetic complexity and prior flaring history. Further C-class activities are expected, with a chance of low M-class flares in the next 24 hours. The position of NOAA 13889 on 15-Nov-2024 at 08:30 UT is: S09W34 (537",-190") 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
by Max Millennium Chief Observer 14 Nov '24

14 Nov '24

Dear Collaborators, Solar activity has slightly increased since the last message. The target region NOAA 13889 (S10W20) continues to be the most flare-productive region on the disk, being the source of seven C-class flares and the largest magnitude flare in the period - an M1.7 at 16:57 UT yesterday (11/13). 13889 retains a beta-gamma-delta magnetic configuration, which is emerging new flux in its trailing portion. The Major Flare Watch shall remain in effect with NOAA 13889 for a further 24 hours due to the possibility of an >M5 flare. The position of NOAA 13889 on 14-Nov-2024 at 08:30 UT is: S10W20 (327",-214") 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.
