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

31 Aug '21

MM#009 Default Target Dear Collaborators, Target region NOAA 2860 continued to decay since the last message losing its beta-gamma magnetic configuration. 2860 was the source of numerous minor B- and C-class events. The largest was a C3.0 at 08/30/21:34 UT. We are ending the MFW today. C-class events likely with only a slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 2860 on August 31 at 14:00 UT is: S27W46 (Solar X = 611", Solar Y = -503") 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 Dear Collaborators, Target region NOAA 2860 has decayed losing much of its magnetic complexity but it still remains a large E-type/beta-gamma region. 2860 was the source of seven B- and six C-class events in the past 24 hours. The largest event was a C2.9 at 08/29/17:30 UT. We will continue the MFW for at least one more day. C-class events expected with a slight chance of an isolated moderate M-class event in the next 24 hour period. The position of NOAA 2860 on August 30 at 14:00 UT is: S27W33 (Solar X =463", Solar Y = -518") 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 Aug '21

29 Aug '21

Dear Collaborators, The level of solar activity is moderate-to-high. Target NOAA 12860 has maintained number of spots and spot area, remaining classified as a beta-gamma/E-type sunspot group. NOAA 12860 has continued to produce multiple C-class flares since the last message, including a C7.4 flare and a C8.1 flare (the largest flare of the period) on 29-Aug-2021 at 00:24 UT and 09:54 UT respectively. Further C-class flares are expected in the following 24-hour period with the Major Flare Watch remaining in effect since NOAA 12860 has the potential for M-class activity. The position of NOAA 12860 on 29-Aug-2021 at 15:00 UT is: S29W18 , ( 257", -557" ) 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 Aug '21

28 Aug '21

Dear Collaborators, Solar activity has increased significantly since the last message. The target region NOAA 12860, now along the central meridian, has produced several C-class flares and an M4.7 flare is currently in progress. We are therefore implementing a Major Flare Watch campaign at this time. The region has increased in size and is now classified as a beta-gamma region. Further intermediate level activity expected over the next 24 hours with chance for a >M5 flare. The position of NOAA 12860 on 28-Aug-2021 at 03:30 UT is: S28E01, ( -14", -548" ) 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 target region NOAA 12860 was the source of several B-class flares since the last message, as well as a C3.9 flare at 23:17 UT yesterday. Former target NOAA 12859 also produced a C3.0 flare at 17:48 UT yesterday. NOAA 12860 remains largely unchanged in terms of size and complexity as it approaches the central meridian. Further B- and C-level activity anticipated over the next 24 hours. The position of NOAA 12860 on 27-Aug-2021 at 11:30 UT is: S30E07, ( -100", -573" ) 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 the B-level with events from NOAA 12859, NOAA 12860, and a new ERF in the northeast quadrant. NOAA 12860 has continued to develop and shall remain the target region. The region retains its beta configuration but continues to undergo flux emergence in its core. Further B-level activity likely with chance for an isolated C-class flare. The position of NOAA 12860 on 26-Aug-2021 at 11:30 UT is: S27E21, ( -304", -526" ) 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 12859 was the source of a C1.5 flare at 14:18 UT yesterday but has since decayed to an alpha region. A large, rapidly emerging region in the southeast quadrant was also the source of a C1 flare at 01:10 UT yesterday and shall be the new target region. The region is designated as NOAA 12860 and has a beta/B-type configuration. Further B- and C-level activity likely from the new target region over the next 24 hours as it continues to develop. The position of NOAA 12860 on 25-Aug-2021 at 11:30 UT is: S28E34, ( -469", -528" ) 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 low levels since the last message. NOAA 12859 remains the source of low B-level activity, including a B8.8 flare at 12:03 UT today. The region remains unchanged in terms of size and complexity, and shall continue as the target region for the next 24 hours. Further B-level activity possible, as well as a chance for a C-class flare. The position of NOAA 12859 on 24-Aug-2021 at 11:30 UT is: N19E39, ( -566", 222" ) 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 12859 in the northeast quadrant has continued to produce B-level activity since the last message, but remains largely unchanged. It retains its beta configuration and shall continue as the target region. Further B-level activity possible with chance for an isolated C-class flare. The position of NOAA 12859 on 23-Aug-2021 at 11:30 UT is: N19E52, ( -708", 240" ) 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 has now been designated as NOAA 12859 and classified as a beta/C-type sunspot group. NOAA 12859 has continued to produce multiple B-class flares since the last message as well as three C-class flares, the largest of which was a C1.9 on 22-Aug-2021 at 10:16 UT. Further B-class flares are expected over the next 24 hours, with a good chance for low-to-mid C-class flares. The position of NOAA 12859 on 22-Aug-2021 at 22:00 UT is: N20E60 , ( -774", 269" ) 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.
