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

31 Mar '24

Dear Collaborators, Solar activity has slightly reduced since the last message. NOAA 13615 produced several flares, the largest being a partially occulted M9.4 at 21:01 UT yesterday. NOAA 13615 has almost passed out of view beyond the southwest limb. As NOAA 13615 continues to produce a substantial number of flares, it will remain the target region. The Major Flare Watch will continue while NOAA 13615 remains in partial view. Further C- and M-class activity is expected with a slight chance for an additional isolated >M5 event in the next 24 hours. The position of NOAA 13615 on 31-Mar-2024 at 11:30 UT is: S13W91, (935",-216") 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 continued at an intermediate level since the last message. NOAA 13615 produced several flares, the largest being an M1.2 at 19:19 UT yesterday. NOAA 13615 continues to produce a substantial number of flares as it transits the southwest limb and still demonstrates a significant level of flux. The Major Flare Watch will continue while NOAA 13615 remains in view, further C-class activity is expected with a chance for isolated (partially occulted) M-class flare or greater in the next 24 hours. The position of NOAA 13615 on 30-Mar-2024 at 12:30 UT is: S13W88, (935",-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 has slightly increased since the last message. NOAA 13615 produced a number of flares, including an X1.1 at 20:50 UT yesterday. NOAA 13615 still shows signs of significant flux as it continues to transit the southwest limb and is persistently producing flares of significant magnitude. The Major Flare Watch will continue with further C- and M-class activity expected and a chance for additional isolated (potentially partially occulted) >M5 activity in the next 24-48 hours. The position of NOAA 13615 on 29-Mar-2024 at 12:30 UT is: S13W76, (909",-188") 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 an intermediate level. NOAA 13615 produced several flares since the last message, the largest being an M7.0 at 06:16 UT today. NOAA 13615 continues to show signs of significant flux and dynamic sunspot behaviour as it begins its transit of the southwest limb. The Major Flare Watch will continue with NOAA 13615 as the target region. Further C- and M-class activity is expected, with a chance of an additional isolated >M5 flare in the next 24-48 hours. The position of NOAA 13615 on 28-Mar-2024 at 12:30 UT is: S13W62, (828",-163") 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 an intermediate level since the last message. NOAA 13615 produced over 20 flares in the last 24 hours, the largest being an M1.9 at 12:55 UT yesterday. NOAA 13615 has grown slightly since the last message and now has an area of 1140 μh. This region remains classified as a beta-gamma-delta. NOAA 13615 continues to show dynamic sunspot behaviour as well as signs of significant flux. The Major Flare Watch will continue as NOAA 13615 begins its approach of the southwest limb. Further C- and M-class activity is likely, with a chance for an isolated >M5 event in the next 24-48 hours. The position of NOAA 13615 on 27-Mar-2024 at 12:30 UT is: S13W48, (698",-141") 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 continued at an intermediate level since the last message. NOAA 13615 has produced a substantial number of flares over the last 24 hours, the largest being an M1.9 at 00:28 UT today. NOAA 13615 has continued to grow in area to 1120 μh and retains its beta-gamma-delta configuration. Given the size, complexity, and significant number of events from NOAA 13615, the Major Flare Watch will continue. Additional C- and M-class activity is expected, with a chance for an isolated >M5 event in the next 24-48 hours. The position of NOAA 13615 on 26-Mar-2024 at 12:30 UT is: S13W34, (525",-123") 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 continued at an intermediate level since the last message. NOAA 13615 has produced 15 flares over the last 24 hours, the largest being an M4.5 at 06:37 UT today. NOAA 13615 remains classified as a beta-gamma-delta type region and has further increased in size to 810 μh. The Major Flare Watch will continue with NOAA 13615 as the target region. Additional >M5 activity is possible over the next 24-48 hours. The position of NOAA 13615 on 25-Mar-2024 at 12:30 UT is: S13W21, (337",-111") 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-moderate level. The largest event since the last message was an M5.4 at 03/23/13:51 UT from the target region NOAA 13615. 13615 also produced more than ten low M-class flares. It was designated as a beta-gamma-delta/F-type configuration, with the area being 730 millionths of the solar disk. Further M-class flares are expected with a good chance of an X-class flare in the next 24 or 48 hours. The position of NOAA 13615 on March 24 at 12:30 UT is: S13W08 (131", -104") 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 level since the last message. The largest "event" was an X1.1 flare at 00:58 UT today produced by the target region NOAA 13615 as well as NOAA 13614 (N17W02, beta/D-type)! 13615 also produced four low M-class flares during the period. It retains a beta-gamma-delta/E-type configuration, with increasing in the number of spots significantly. Additional M-class flares are expected with a chance of another X-class flare in the next one or two days. The position of NOAA 13615 on March 23 at 08:30 UT is: S13E05 (-82", -102") 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 level since the last message, with the largest event being a C8.7 flare at 11:25 UT yesterday produced by the target region NOAA 13615. 13615 also produced another five C-class flares during the period. It remains a beta-gamma-delta/ E-type configuration. Today we continue the Major Flare Watch on this region due to its growing current helicity. Please note that another region, NOAA 13614 (N17E11), also produced five C-class flares including a C8.4 at 13:45 UT today, which has a beta/D-type sunspot group. Further C-class activities are expected, with a chance of an isolated flare above M5 in the next few days. The position of NOAA 13615 on March 22 at 16:30 UT is: S12E15 (-244", -88") 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.
