MM#009 Default Target
by Max Millennium Chief Observer 11 Jul '23

11 Jul '23

Dear Collaborators, The largest event since the last message was an M1.5 produced by NOAA 13358. 13358 also produced more than five C-class flares in the period. Today the target will switch to this region, although it rotates over the west limb. 13358 is still emerging with new magnetic fluxes. Yesterday's target region NOAA 13361 was the source of only two low C-class flares and remains a beta- gamma-delta/E-type configuration. Please note that a northeast limb region (N22E88) produced about ten C-class flares (the largest one being a C8.0) before it rotates on the visible disk. Further C-class activities are expected with a chance of a low M-class flare in the next 24 hours. The position of NOAA 13358 on July 11 at 07:30 UT S13W68 (853", -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, Solar activity has been at an intermediate level since the last message. The largest event in the period was an M2.4 flare at 07/10/03:29 UT from NOAA 13358 that has an alpha/A-type sunspot group. Multiple C-class flares were produced by various regions, including NOAA 13358, 13368, 13366, 13367, and 13361, with the largest one being a C9.4 at 07/10/01:49 UT from the target region NOAA 13361. 13361 has been designated as a beta-gamma-delta/E-type configuration. We will watch this region for a further 24 hours. Additional C-class flares are expected from various regions with a good chance for a low M-class flare in the next 24 hours. The position of NOAA 13361 on July 10 at 07:30 UT N24W30 (432", 334") 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 C-level since the last message, the largest event being a C5.7 flare from NOAA 13366 at 00:05 UT today. NOAA 13361 has also remained active and shall continue as the target region. It retains its beta-delta configuration and shows signs of further development. Sustained intermediate level activity likely over the next 24 hours. The position of NOAA 13361 on 9-Jul-2023 at 11:30 UT is: N24W19, ( 281", 331" ) 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 low C-level since the last message, although NOAA 13359 has remained quiescent and shown signs of decay. Much of the activity has come from NOAA 13361 in the northern hemisphere, which is now classified as a beta-delta/E-type region and continues to develop. NOAA 13361 shall be the new default target region with further intermediate level activity expected over the next 24 hours. The position of NOAA 13361 on 8-Jul-2023 at 15:30 UT is: N24W07, ( 105", 330" ) 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 13354 has now rotated beyond the western limb. A large (~400uh) alpha sunspot, designated NOAA 13363, has rotated into view on the southeast limb but has so far remained quiescent. The new target region shall be NOAA 13359, a beta/D-type active region in the southwest quadrant. It has been the source of several C-class flares since the last message, as well as an M4.0 flare at 06:17 UT today. Further intermediate level activity likely over the next 24 hours. The position of NOAA 13359 on 7-Jul-2023 at 11:30 UT is: S21W22, ( 331", -388" ) 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 intermediate levels with NOAA 13354 now behind the northwest limb. The region has produced two partially occulted M1 flares since the last message and shall remain the target region for a further 24 hours, although we are ending the Major Flare Watch campaign at this time. Further C-level activity possible with slight chance of an isolated low M-class flare. The approximate position of NOAA 13354 on 6-Jul-2023 at 11:30 UT is: N15W90, ( 911", 243" ) 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 05 Jul '23

05 Jul '23

Dear Collaborators, NOAA 13354 is now on the northwestern limb and has continued to produce C-level activity since the M1.5 flare yesterday. It remains classified as a beta-gamma-delta region although its precise size and magnetic configuration are uncertain at this time. We shall continue with the Major Flare Watch campaign in effect for a further 24 hours due to the possibility of an >M5 flare before the region rotates behind the western limb. The position of NOAA 13354 on 5-Jul-2023 at 07:30 UT is: N16W91, ( 906", 260" ) 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 04 Jul '23

04 Jul '23

Dear Collaborators, Solar activity has continued at the C-level since the X-class flare from NOAA 13354 two days ago with events from multiple regions across the visible solar disk. An M1.4 flare from the target region is also currently in progress. The region retains its beta-gamma-delta configuration as it approaches the northwestern limb and the Major Flare Watch campaign shall remain in effect due to the possibility of an >M5 flare before west limb transit. The position of NOAA 13354 on 4-Jul-2023 at 11:30 UT is: N16W79, ( 890", 250" ) 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 03 Jul '23

03 Jul '23

Dear Collaborators, The target region NOAA 13354 was the source of an X1.1 flare at 22:54 UT yesterday. The region retains its beta-gamma-delta configuration and has increased in area to over 1100uh due to continued flux emergence in its leading sunspot. As such we are implementing a Major Flare Watch campaign at this time due to the increased likelihood of another >M5 flare before the region transits the northwest limb. The position of NOAA 13354 on 3-Jul-2023 at 11:30 UT is: N16W65, ( 823", 239" ) 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 a moderate level since the last message. The largest event in the period was an M2.1 compact flare from NOAA 13359 (S20E57, beta/D-type) at 02:29 UT today. 13359 also produced another M-class (M1.1) plus five C-class flares in the period. The target region NOAA 13354 retained a beta-gamma-delta/F-type configuration and underwent flux emergence in its north- western portion, which produced a few C-class flares in the period. The target remains with 13354 due to its magnetic complexity and past flaring history. More C-class events are expected in the following 24-hour period, with a good chance for additional M-class flares. The position of NOAA 13354 on 2-Jul-2023 at 11:30 UT is: N13W51 (716", 182") 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.
