MM#009 Default Target
by Max Millennium Chief Observer 19 Jun '24

19 Jun '24

Dear Collaborators, Solar activity has been at a moderate-to-low level since the last message. The largest event in the past 24 hours was an M1.2 flare at 06:15 UT today produced by NOAA 13711 that has a beta/B-type configuration and is now located near the west limb (S11W79). Another two regions, NOAA 13713 (S16W25, beta-gamma/E-type) and 13716 (N10W31, beta-gamma/ D-type), produced four low C-class flares (two from each). The target region NOAA 13712 retains a beta-gamma-delta/ E-type configuration but did not show any notable activity in the period. At this moment, we end the Major Flare Watch campaign but continue to watch NOAA 13712. If possible, please also include NOAA 13713 in your field of view. Low M-class activities are likely from these three regions in the next 24 hours. The position of NOAA 13712 on June 19 at 19:30 UT is: S26W37 (512", -434") 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 target region NOAA 13712 produced two M-class flares (an M2.4 at 11:14 UT and an M1.2 at 12:11 UT today) and more than ten C-class flares. It retains a beta-gamma-delta/E-type configuration with increasing the sunspot area (to 1100 μh) and number of spots slightly. We will continue the Major Flare Watch campaign on this region. Low M-class activity is expected with a chance of a >M5 flare in the next 1-2 days. The position of NOAA 13712 on June 18 at 19:30 UT is: S26W23 (332", -435") 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 moderate levels since the last message. The target region NOAA 13712 produced two M1.6 flares today (at 07:54 and 10:42 UT, with the largest magnitude) and more than ten C-class flares. Note that another region NOAA 13711 (S11W54, alpha/D-type) also produced an M1.4 flare at 19:57 UT today. The target NOAA 13712 maintains a beta-gamma-delta/E-type configuration and continues showing new magnetic flux emergence. The Major Flare Watch campaign will continue, with M-class activities expected and a good chance of a >M5 flare in the next few days. The position of NOAA 13712 on June 17 at 19:30 UT is: S26W10 (147", -435") 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 target NOAA 13712 (S25E03) continued to be the most flaring region on disk, being the source of more than twenty C-class flares, including the largest magnitude in the period - a C7.2 flare on 15-Jun-2024 at 23:15 UT. 13712 remains a beta-gamma-delta configuration with an approximate area of 850 μH. This region continues to show signs of emerging flux and dynamic sunspot behaviour. Today, we will continue the Major Flare Watch campaign on NOAA 13712 due to the possibility of an isolated >M5 flare in the next 24–48 hours. The position of NOAA 13712 on 16-Jun-2024 at 19:30 UT is: S25E03 (-44",-419") 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 level since the last message. The target NOAA 13712 (S24E16) remains the most flare-productive region on disk, being the source of approximately thirty C-class flares and the largest magnitude flare in the period - an M1.3 at 06:00 UT today. 13712 has now developed into a beta-gamma-delta region, with an increase in sunspot area and number of spots. This region continues to show signs of emerging flux and dynamic sunspot behaviour in its intermediate portion. At this time, we are implementing a Major Flare Watch campaign on NOAA 13712 due to the possibility of an isolated >M5 flare. The position of NOAA 13712 on 15-Jun-2024 at 15:30 UT is: S24E16 (-238",-401") 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. Yesterday's target region NOAA 13713 (S13E45, beta/D-type) produced three C-class flares since the last message. The largest event in the period was an M2.4 flare at 04:14 UT today from the nearby region NOAA 13712 (S24E29) mentioned in the previous message. 13712 was the most flare-productive region in the period, which also produced another more than ten C-class flares and has developed into a beta-gamma region. This region continues to undergo flux emergence and is showing mixed polarities in the intermediate portion. Today the target shall switch to NOAA 13712. Further C-class activity is expected, with a chance for an isolated low M-class flare. The position of NOAA 13712 on 14-Jun-2024 at 15:30 UT is: S24E29 (-419",-398") 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 level since the last message. The target region has now been numbered as NOAA 13713 (S13E59, beta/D-type) and produced the largest event during the period - an M3.2 flare at 16:34 UT today. This region and a nearby region NOAA 13712 (S24E43, beta/D-type) also produced several C-class flares in the period. The default target will remain as NOAA 13713 due to the continued flux emergence in its intermediate portion. If possible, please also include the nearby region 13712 in the field of view, which is showing significant magnetic flux emergence as well. Please note that NOAA 13711 (S09E03, beta/B-type) also produced an M1.2 flare in the period. Further C-class activity is expected, with a good chance for additional low M-class flares. The position of NOAA 13713 on 13-Jun-2024 at 15:30 UT is: S13E59 (-790",-220") 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 low level. Yesterday's target NOAA 13697 has nearly rotated beyond the west limb. The largest event since the last message was a C4.4 flare at 12:53 UT today from a southeast limb region (S09E79, unnumbered yet). This region also produced a C2.5 flare in the period. Two nearby active regions, NOAA 13711 (S08E16, beta/D-type) and NOAA 13709 (S09E04, beta/D-type), also produced several low C-class flares in the period, but these two regions have shown a decay in the sunspot area. At this moment, we shall end the Major Flare Watch campaign and the target region will switch to the southeast limb region. C-class activities are expected in the next 24 hours. The approximate position of the target region on 12-Jun-2024 15:30 UT is: S09E79 (-916",-150") 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. Target region NOAA 13697 has now rotated over the South West limb, with some overlying loops visible above the limb. This region produced numerous C-class flares and the largest magnitude flare in the period - an M9.6 on 10-Jun-2024 at 18:11 UT. The Major Flare Watch shall remain in effect with NOAA 13697 for a final 24 hours, as it rotates fully out of view beyond the South West limb. Further C-class activity is expected, with a slight chance for an isolated low M-class flare. The position of NOAA 13697 on 11-Jun-2024 at 15:30 UT is: S19W91 (892",-307") 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 high level since the last message. The largest event was an X1.6 flare at 11:03 UT, happening just now, produced by the target region NOAA 13697 (S19W91). This region also produced another four M-class flares (M1.0, M3.3, M2.3, and M5.3) and several C-class flares during the period. Today we will continue the Major Flare Watch campaign on NOAA 13697 before it completely rotates over the west limb. Further C- and M-class activity is expected, with a chance for additional >M5 flares. The position of NOAA 13697 on 10-Jun-2024 at 11:30 UT is: S19W91 (892",-307") 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.
