MM#009 Default Target
by Max Millennium Chief Observer 31 Aug '22

31 Aug '22

Dear Collaborators, Solar activity has returned to intermediate levels now that NOAA 13088 is behind the southwestern limb. The region produced a long-duration M2.1 flare at 18:04 UT yesterday before parting. NOAA 13089 has been downgraded to a beta-gamma region and has halved in size since the last message. It shall be the new target region with further C-level activity expected over the next 24 hours. The position of NOAA 13089 on 31-Aug-2022 on 11:30 UT is: S22W13, ( 198", -462" ) 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 diminished in the past 24 hours with NOAA 13088 now beyond the western limb. The region produced five M-class flares since the last message, including an M4.7 around 17:00 UT yesterday. NOAA 13089 along the central meridian is now classified as a beta-gamma-delta region with an area of >500uh but is largely quiescent. The looptops of NOAA 13088 on the southwest limb shall remain the target region but we will be ending the Major Flare watch campaign at this time. Only intermediate level activity expected. The position of NOAA 13088 on 30-Aug-2022 at 11:30 UT is: S27W91, ( 845", -425" ) 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 '22

29 Aug '22

Dear Collaborators, Solar activity remains at high levels with NOAA 13088 having produced an M8.6 flare at 10:48 UT today, as well as two other mid-M flares since the last message. The region is now located behind the southwest limb and its size and magnetic configuration are no longer known. However it shall remain the target region with a Major Flare Watch in effect. Chance remains for an additional >M5 flare in the next 24 hours. The position of NOAA 13088 on 29-Aug-2022 at 11:30 UT is: S27W91, ( 845", -425" ) 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 '22

28 Aug '22

Dear Collaborators, Solar activity has been at a moderate to high level since the last message. The largest event of the period was an M6.7 flare at 08/28/15:48 UT produced by NOAA 13088. 13088 also produced four low M-class flares with the largest one being an M1.8 at 08/27/15:45 UT. Today the Major Flare Watch region will switch to NOAA 13088, though it is rotating beyond the west limb. This region was designated as a beta-gamma/D-type configuration. Additional M-class flares are probable in the next 24 hours. The position of NOAA13088 on August 28 at 15:30 UT is: S27W82 (837", -442") 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 27 Aug '22

27 Aug '22

Dear Collaborators, Solar activity has been at a high level for the past 24 hours. The target region NOAA 13089 was the source of two major flares, an M7.2 at 08/26/12:08 UT and an M5.3 at 08/26/12:24 UT. Moreover, NOAA 13088 (S28W62) produced 5 low M-class flares, the largest one being an M4.8 at 08/27/01:52 UT. Today we will implement the Major Flare Watch campaign. The target region 13089 has been designated as a beta-gamma/D-type configuration. 13088 has a beta/D-type sunspot group but significantly increases the sunspot area. More low M-class activities are expected with a chance of additional major flares from these two regions. The position of NOAA13089 on August 27 at 07:30 UT is: S21E40 (-571", -422") 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 increased further in the past 24 hours. The two unnumbered active regions mentioned in the last message have been designated as NOAA 13088 and 13089 (target region), both of which have a beta/D-type sunspot group. These two regions were the sources of numerous (about 20) C-class flares and in particular, the target region NOAA 13089 produced three low M-class flares, an M1.8 (08/25/19:39 UT), an M1.0 (08/25/23:21 UT), and an M2.1 (08/26/10:41 UT). Both regions show an opposite flux emerging in the core. Additional M-class flares are probable in the next two days. The position of NOAA13089 on August 25 at 07:30 UT is: S24E52 (-684", -449") 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. There were numerous B- and low C-class flares produced by two unnumbered regions, one near the east limb (S23E64) and the other rotating to the west limb (S27W41). The former region produced the largest event of the period, a C3.6 at 08/25/09:53 UT. Today the target will switch to this region, which seems to be emerging with new magnetic fluxes. Yesterday's region NOAA 13085 has been flare quiet, though it still has a beta/D-type sunspot group. Further C-class activities are expected from the above two unnumbered regions in the next 24 hours. The approximate position of the target region on August 25 at 11:30 UT is: S23E64 (-800", -400") 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 an extremely low level with the soft X-ray flux below C1. The target region NOAA 13085 was the source of five B-class flares in the past 24 hours, the largest one being a B5.8 at 08/23/15:32 UT. 13085 remains its beta/D-type configuration but increasing in the sunspot area and number of spots. It shows some mixed polarities in its intermediate portion. Only low level activities are expected in the following 24 hours. The position of NOAA 13085 on August 24 at 07:30 UT is: N25W12 (179", 296") 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 a very low level. The largest event since the last message was a C5.0 flare at 08/22/14:01 UT emergent from target region NOAA 13085. 13085 was also the source of five low C-class flares during the period. Some other regions (NOAA 13084, 13081, and a southeast limb region) also produced a ~C1 flare from each. Target region 13085 retains its beta/D-type configuration and still shows flux emerging especially in its trailing portion. Additional C-class activities are expected in the next 24 hours. The position of NOAA 13085 on August 23 at 07:30 UT is: N30W03 (43", 372") 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 a very low level. The largest event since the last message was a C2.4 flare at 08/21/23:31 UT produced by a newly emerged region NOAA 13085. 13085 also produced another seven ~C1 flares. It has been designated as a beta/D-type configuration. Today the target will switch to this region. Yesterday's target NOAA 13078 only produced a C2.0 flare and now it has rotated beyond the west limb. Further C-class activities are expected from 13085 in the next 24 hours. The position of NOAA 13085 on August 22 at 07:30 UT is: N29E12 (-173", 359") 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.
