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

23 Dec '23

Dear Collaborators, Solar activity has diminished since the last message. NOAA 13519 is now beyond the southwest limb but continued to produce a few partially occulted C2 flares. The looptops remain visible in EUV images and the region shall continue as the target region for a further 24 hours. Isolated C-class flares possible. The position of NOAA 13519 on 23-Dec-2023 at 12:30 UT is: S10W91, ( 959", -169" ) 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, NOAA 13519 has continued to produce C-level activity, as well as an M3.3 flare at 23:42 UT yesterday, as it approaches the southwest limb. Its magnetic configuration is uncertain at this time but it shall continue as the target region for the next 24 hours. Further C-level activity likely with chance for an additional low M-class flare before west limb passage. The position of NOAA 13519 on 22-Dec-2023 at 12:30 UT is: S12W79, ( 936", -197" ) 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 moderate levels since the last message, although NOAA 13521 has remained quiescent. NOAA 13519 near the southwest limb was the source of an M4.2 flare at 05:19 UT today and shall be the new target region. The region has undergone significant flux emergence ahead of its leader spot and appears to have a complex magnetic configuration. Further C-class flares likely with chance of an additional low M-flare before west limb passage. The position of NOAA 13519 on 21-Dec-2023 at 12:30 UT is: S11W65, ( 868", -174" ) 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 intermediate levels, with C-level activity from multiple regions across the solar disk. NOAA 13528 has remained quiescent since the last message, while nearby NOAA 13521 has produced several high C-class flares as it has developed over the past few days. It is currently classified as a beta/C-type region and is showing signs of additional flux emergence in its core. NOAA 13521 shall be the new target region with further high-C/low-M level activity possible over the next 24 hours. The position of NOAA 13521 on 20-Dec-2023 at 12:30 UT is: N12E12, ( -199", 228" ) 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. Several C-class flares were produced, the largest being a C7.4 at 02:56 UT today from newly number active region NOAA 13528. This region is currently classified as a beta-delta type region and has shown dynamic sunspot behaviour over the last 24 hours. The target region will switch to NOAA 13528, with a chance for continued C-class activity over the next 24 hours. The position of NOAA 13528 on 19-Dec-2023 at 12:30 UT is: N09E05, (-84",176") 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, NOAA 13514 has now passed beyond the northwest limb. Several flares were produced over the last 24 hours, the largest being an occulted M1.1 at 20:08 UT yesterday attributed to NOAA 13520 at the northwest limb. A region of significant flux is now visible at the northeast limb about NOAA 13526 and a number of flares have been produced in this region since the last message. At this time we are ending the Major Flare Watch campaign and switching the target region to the northeast limb in proximity to NOAA 13526 for the next 24 hours. Further C-class activity is expected. The position of NOAA 13526 on 18-Dec-2023 at 12:30 UT is: N15E62, (-832", 262") 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 17 Dec '23

17 Dec '23

Dear Collaborators, Solar activity has remained at an intermediate level since the last message. NOAA 13514 produced a further twelve C-class flares since the last message, the largest being a C8.4 at 13:19 UT yesterday. The Major Flare Watch will be extended for a further 24 hours, with a slight chance for a partially occulted M-class flare as NOAA 13514 continues its transit beyond the northwest limb. The approximate position of NOAA 13514 on 17-Dec-2023 at 13:00 UT is: N5W89, (971", 85") 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 16 Dec '23

16 Dec '23

Dear Collaborators, Solar activity has remained at an intermediate level since the last message. NOAA 13514 produced several C-class flares, the largest being a C5.5 at 21:12 UT yesterday. NOAA 13514 is currently classified as a beta-gamma-delta type region. The Major Flare Watch will be extended for a further 24 hours as NOAA 13514 begins its transit of the northwest limb, with a slight chance for an isolated >M5 event. The position of NOAA 13514 on 16-Dec-2023 at 12:30 UT is: N05W75, (938", 89") 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 15 Dec '23

15 Dec '23

Dear Collaborators, Solar activity has further increased since the last message. NOAA 13514 produced a number of significant flares in the last 24 hours, the largest being an X2.8 at 16:47 UT yesterday. NOAA 13514 is now classified as a beta-delta type region and has shown a substantial increase in both area and number of spots. This region continues to show dynamic sunspot behaviour. The Major Flare Watch will be extended for a further 24 hours, with a chance for additional >M5 activity. The position of NOAA 13514 on 15-Dec-2023 at 12:30 UT is: N05W57, (816", 93") 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.

14 Dec '23

Dear Collaborators, Solar activity has slightly increased since the last message. NOAA 13514 produced several flares over the last 24 hours, the largest being an M5.8 at 07:11 UT today. NOAA 13514 continues to show dynamic sunspot behaviour. At this time we are implementing a Major Flare Watch with NOAA 13514 as the target region. Further >M5 activity possible over the next 24-48 hours. The position of NOAA 13514 on 14-Dec-2023 at 12:30 UT is: N07W43, (661", 128") 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.
