MM#003 Major Flare Watch
by Max Millennium Chief Observer 11 Jan '23

11 Jan '23

Dear Collaborators, Solar activity has been at high levels for the past 24 hours. The largest event since the last message was an X1.0 flare at 01/10/22:39 UT produced by the northeast limb region mentioned in the last message, now numbered as NOAA 13186. 13186 also produced three low M-class flares (M1.4, M2.4, and M3.1) and six C-class flares. Today the Major Flare Watch region will switch to NOAA 13186 that has been classified as a beta-delta/D-type configuration. Yesterday's target NOAA 13184 (S13E48) produced an M5.6 flare at 01/11/01:49 UT and also an M1.2 plus two C-class flares. This region has been designated as a beta-delta/ E-type region. In addition, NOAA 13181 produced an M1.3 flare and was designated as a beta-gamma/E-type region. Further M-class (including above M5) flares are expected from various regions in the next 24-48 hours. The position of NOAA 13186 on January 11 at 08:30 UT N25E60 (-766", 443") 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 was at a high level in the past 24 hours. The target region NOAA 13184 produced an X1.9 flare at 01/09/18:37 UT and also two M1 plus a few C-class flares. 13184 retains an alpha/H-type configuration but increases in the sunspot area and number of spots. Today the Major Flare Watch will remain in effect with NOAA 13184. In addition, an M5.1 flare was produced by a northeast limb region (N24E79). Please also note that NOAA 13181 (S19W40) produced an M2.7 flare at 01/10/02:33 UT, which has been classified as a beta-gamma-delta/E-type region. Further M-class flares are probable from various regions in the next 24-48 hours. The position of NOAA 13184 on January 10 at 12:30 UT S14E60 (-821", -202") 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 moderate level. The largest event since the last message was an M2.1 flare at 01/09/08:45 UT produced by NOAA 13181 (S20W27). 13181 has been designated as a beta-gamma/E-type configuration, with emerging new sunspots and new magnetic fluxes. The target region NOAA 13182 only produced a few low-to-mid C-class flares since the last message, though it has been classified as a beta-gamma-delta/E-type configuration. Today the Major Flare Watch region will switch to the southeast limb region, now numbered as NOAA 13184, which has produced five ~M1 flares. But if possible, please also include NOAA 13182 (S17E25) in your field of view. Additional low M-class flares are expected from various regions with a chance of an above M5 flare in the next 24-48 hours. The position of NOAA 13184 on January 9 at 12:30 UT S13E74 (-914", -201") 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 13182 has produced sustained C-level activity since the last message. There was also an occulted M1.2 flare from behind the southeast limb at 08:39 UT today. NOAA 13182 has continued to develop and is now classified as a beta-gamma-delta region due to mixed polarities in the trailing spots. Major Flare Watch shall remain in effect with NOAA 13182 as the target region, but also include the approaching region behind the southeast limb in your field of view as well if possible. The position of NOAA 13182 on 8-Jan-2023 at 08:30 UT is: S17E41, ( -613", -238" ) 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 13182 has continued to produce C-level activity since the X-class flare yesterday, as well as an M1.6 flare at 00:40 UT today. There have also been mid C-class flares from NOAA 13183 in the southwest quadrant, and NOAA 13181 has shown signs of rapid development along the central meridian, but has so far remained quiescent. NOAA 13182 is now classified as a beta-gamma region with an area of almost 500 uH, and shall continue as the target region with a Major Flare watch in effect. Chance remains for an additional >M5 flare. The position of NOAA 13182 on 7-Jan-2023 at 04:30 UT is: S16E56, ( -779", -235" ) 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 new target region near the southeast limb has now been designated as NOAA 13182 and was the source of an X1.2 flare at 00:43 UT today. As such we are implementing a Major Flare Watch campaign at this time. The region is currently classified as a simple beta/D-type region but may show signs of complexity as it rotates on to the disk. Increased chance of additional >M5 flaring over the next 24-48 hours. The position of NOAA 13182 on 6-Jan-2023 at 04:30 UT is: S17E69, ( -872", -264" ) 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#009 Default Target
by Max Millennium Chief Observer 05 Jan '23

05 Jan '23

Dear Collaborators, Despite its beta-gamma configuration NOAA 13180 has remained quiescent since the last message. The new region now visible on the southeast limb, however, has continued to produce C-level activity, including a C6.8 flare at 07:42 UT today, and shall be the new target region. It is currently unnumbered and its magnetic configuration is uncertain at this time but further intermediate level activity is expected over the next 24 hours. The approximate position of the target region on 5-Jan-2023 at 12:30 UT is: S19E87, ( -921", -314" ) 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#009 Default Target

04 Jan '23

Dear Collaborators, Solar X-ray flux has remained at the low C-level since the last message with a few C2 flares from the region currently behind the southeast limb. NOAA 13180 has remained quiescent but is now classified as a beta-gamma region as it approaches the central meridian. NOAA 13180 shall continue as the target region for a further 24 hours with a chance of isolated, intermediate level events. The position of NOAA 13180 on 4-Jan-2023 at 12:30 UT is: N18E10, ( -161", 356" ) 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 13180 has continued to produce low C-class flares since the last message. There is also a new region currently behind the southeast limb that was the source of a long duration C2.4 flare at 07:41 UT day. NOAA 13180 maintains its beta/D-type configuration but has shown signs of flux emergence and polarity mixing in its trailing portion. It shall continue as the target region with further C-level activity likely over the next 24 hours. The position of NOAA 13180 on 3-Jan-2023 at 12:30 UT is: N19E23, ( -361", 366" ) 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 since the last message, with isolated C-class flares from both NOAA 13176 and NOAA 13180. The largest event was a C9.4 flare at 06:09 UT today from NOAA 13176, which has since decayed significantly. NOAA 13180 remains largely unchanged and shall continue as the target region for a further 24 hours. Additional isolated C-class flares possible. The position of NOAA 13180 on 2-Jan-2023 at 16:30 UT is: N19E33, ( -504", 361" ) 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.
