MM#009 Default Target
by Max Millennium Chief Observer 31 Oct '21

31 Oct '21

Dear Collaborators, Solar activity has diminished over the last 24 hours. NOAA 12887 and NOAA 12891 have continued to produce low C-level activity. NOAA 12887 retains its beta-gamma configuration but has decayed significantly. It shall remain the target region for a further 24 hours although we are ending the Major Flare Watch at this time. Additional intermediate level activity is expected. The position of NOAA 12887 on 31-Oct-2021 at 12:30 UT is: S28W40, ( 549", -504" ) 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 30 Oct '21

30 Oct '21

Dear Collaborators, C-level activity from both NOAA 12887 and 12891 has continued since the last message, with NOAA 12891 producing a C9.0 flare at 13:33 UT today. The target region NOAA 12887 has retained its beta-gamma configuration and maintains mixed polarities in its trailing portion. Major Flare Watch shall remain in effect for a further 24 hours, with a slight chance of an M5 flare or greater in the next 24 hours. The position of NOAA 12887 on 29-Oct-2021 at 23:30 UT is: S26W22, ( 326", -488" ) 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 29 Oct '21

29 Oct '21

Dear Collaborators, Solar activity remains high. The largest event since the last message was an M1.5 flare from NOAA 12891 in the northeast quadrant. The target region NOAA 12887 has remained relatively quiescent since the X-class flare yesterday, and has continued to decay. It retains its beta-gamma configuration, with signs of polarity mixing in its trailing portion. Major Flare Watch shall remain in effect with chance for an additional >M5 flare over the next 24 hours. The position of NOAA 12887 on 29-Oct-2021 at 07:30 UT is: S26W12, ( 181", -492" ) 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 28 Oct '21

28 Oct '21

Dear Collaborators, The target region NOAA 12887 has just produced an X1.0 flare at beginning 15:17 UT today. At this time we are implementing a Major Flare Watch due to the increased likelihood of another >M5 flare in the next 24 hours. The position of NOAA 12887 on 28-Oct-2021 at 15:30 UT is: S26W05, ( 75", -494" ) 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 elevated although NOAA 12891 has remained relatively quiescent. Much of the C-class activity over the past 24 hours, and the M1.4 flare at 07:30 UT today, has come from NOAA 12887. This shall be the default target region once again. The region currently has a beta-gamma configuration, but is showing signs of decay as it crosses the central meridian. Further C-level activity expected, with chance for an additional isolated M-class flare. The position of NOAA 12887 on 28-Oct-2021 at 07:30 UT is: S26W00, ( 0", -495" ) 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. The target region along the northeast limb has now been designated as NOAA 12891, and has produced some low C-level activity since the last message. Former target region NOAA 12887 produced a C8.5 flare at 05:47 UT today. NOAA 12891 appears to be a compact beta region and shall continue as the target region for a further 24 hours. Additional B- and C-level activity possible. The position of NOAA 12891 on 27-Oct-2021 at 11:30 UT is: N20E71, ( -858", 304" ) 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 due to a new active region currently behind the northeast limb. The region has produced several high C-class flares over the past few hours as well as an M1.3 flare at 02:40 UT today. While the magnetic configuration is uncertain at this time, this shall be the new target region. Further C-level activity is expected with chance for an additional M-class activity as the region rotates into view. The approximate position of the target region on 26-Oct-2021 at 07:30 UT is: N14E85, ( -933", 226" ) 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 low levels. NOAA 12887 retains its beta configuration and has produced mid B-level flares since the last message, as has newly emerged NOAA 12888 in the southwest quadrant. NOAA 12887 shall continue as the target region for a further 24 hours, with additional B-level activity likely. Also include NOAA 12888 in your field of view as well if possible. The position of NOAA 12887 on 25-Oct-2021 at 11:30 UT is: S25E33, ( -477", -471" ) 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 very low level. Target NOAA 12887 has remained stable and continues to be classified as a beta/D-type sunspot group. 12887 has continued producing B-class activity since the last message. Further B-class activity is expected in the following 24-hour period. The position of NOAA 12887 on 24-Oct-2021 at 17:00 UT is: S26E44 , ( -603", -478" ) 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. The target region has now been designated as NOAA 12887 and is classified as a beta/D-type sunspot group. This region has continued to produce B-class activity since the last message, including the largest flare of the period (a B5.4 on 23-Oct-2021 at 02:19 UT). Additional B-class flares are expected over the next 24 hours, with a chance for a C-class flare. The position of NOAA 12887 on 23-Oct-2021 at 16:30 UT is: S24E56 , ( -732", -436" ) 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.
