MM#009 Default Target
by Max Millennium Chief Observer 08 Feb '22

08 Feb '22

Dear Collaborators, Solar activity has remained around the C1 level since the last message. NOAA 12941 was the source of a C1.2 flare at 22:57 UT yesterday. The region has undergone flux emergence in its core, but retains its beta/E-type configuration. It shall continue as the target region with low-level activity possible over the next 24 hours. The position of NOAA 12941 on 8-Feb-2022 at 12:30 UT is: N25E17, ( -258", 505" ) 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 C-level since the last message due to a resurgence from NOAA 12936 currently behind the northwest limb. The target region in the northeast quadrant, NOAA 12941, has remained quiescent and unchanged, and retains its beta/E-type configuration. It shall continue as the target region for a further 24 hours, although only isolated low-level events are likely at this time. The position of NOAA 12941 on 7-Feb-2022 at 12:30 UT is: N24E28, ( -418", 482" ) 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. Target region NOAA 12936 has now rotated its spots over the North West limb. Most of the spotted regions on the visible disk have shown signs of slight decay since the last message. The target switches to NOAA 12941, a beta/E-type classified sunspot group that was the source of four low C-class flares shortly after the last message was issued. Further C-class activity is expected in the next 24 hours. The position of NOAA 12941 on 6-Feb-2022 at 16:30 UT is: N24E39 , ( -562", 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 low level. Target region NOAA 12936 showed signs of decay but it has remained as a beta/E-type sunspot classification. This region has continued to flare since the last message, producing six low C-class flares including the largest of the period (a C2.6 on 4-Feb-2022 at 21:42 UT). Although NOAA 12936 is now rotating over the North West limb, it will remain the target for the next 24 hours while its high-lying loops remain visible. Additional C-class flares are expected in the following 24-hour period, with a small chance for a low M-class flare. The position of NOAA 12936 on 5-Feb-2022 at 22:00 UT is: N17W87 , ( 929", 288" ) 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. Target region NOAA 12940 decayed slightly since the last message and has simplified in magnetic classification to a beta/C-type sunspot group. This region did not produce any flaring activity since the last message, so the MMCO target switches back to NOAA 12936 as it rotates up to the North West limb. NOAA 12936 has remained as a beta/E-type sunspot classification but has increased in its frequency of flaring to produce eight C-class flares over the past 24 hours, including the largest of the period (a C5.8 on 4-Feb-2022 at 15:39 UT). Additional C-class activity is likely in the next 24 hours, with a chance for a low M-class flare. The position of NOAA 12936 on 4-Feb-2022 at 18:00 UT is: N17W72 , ( 885", 315" ) 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. The target region NOAA 12940 has decayed somewhat in sunspot area over the past 24 hours and remains classified as a beta-gamma/D-type sunspot group. There are several spotted NOAA regions that produced C-class activity since the last message, including NOAA 12940. Further C-class activity is expected over the following 24-hour period, with a chance for a low M-class flare. The position of NOAA 12940 on 3-Feb-2022 at 18:00 UT is: N18E23 , ( -365", 392" ) 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 at a low-to-moderate. The target region NOAA 12936 has shown mixed signs of decay and new sunspot development, remaining classified as a beta/E-type sunspot group. This region continued producing only low C-class activity since the last message, so the Max Millennium coordinated observing plan #003 (Region Likely To Produce A Major Flare) will cease at this time. Although NOAA 12936 is expected to produce additional C-class activity, the target region switches to NOAA 12940. This region is classified as a beta-gamma/D-type sunspot group and has been the source of several low-to-mid C-class flares since the last message. Further C-class activity is expected, with a chance for a low M-class flare. The position of NOAA 12940 on 2-Feb-2022 at 23:30 UT is: N18E20 , ( -320", 394" ) 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 01 Feb '22

01 Feb '22

Dear Collaborators, Solar activity is at a low-to-moderate level. The target NOAA 12936 continued to evolve its interior spots since the last message, but retained a classification as a beta/E-type sunspot group. The most flare-productive region has been newly numbered NOAA 12940 in the North West quadrant that produced several C-class events including the largest flare of the period (a C8.6 on 1-Feb-2022 at 07:25 UT). Whilst NOAA 12940 is expected to produce more C-class flares and it has the potential for low M-class, NOAA 12936 remains the target of the current Max Millennium coordinated observing plan #003 (Region Likely To Produce A Major Flare) for another 24 hours. This is due to the leading spots of NOAA 12938 (that appear to be showing minor flux emergence) being relatively close to the opposite-polarity and irregularly-shaped main trailing spot of NOAA 12936. The position of NOAA 12936 on 1-Feb-2022 at 20:00 UT is: N16W33 , ( 511", 351" ) 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.
