MM#003 Major Flare Watch
by Max Millennium Chief Observer 22 Jul '26

22 Jul '26

Dear Collaborators, Solar activity has persisted at a low to moderate level. Multiple flares have been produced since the last message, the largest being an M3.6 from NOAA 14493 at 06:27 UT today. NOAA 14493 remains highly productive, retaining its beta-gamma-delta classification and more than doubling in size. While we are yet to see a major flare from this region, the high level of flux and sunspot dynamism warrants the continuation of the major flare watch campaign. The major flare watch will remain active for the next 24 hours. Further C- and low M-class activity is likely with a slight chance for an isolated >M5.0 event. The position of NOAA 14493 on 22-July-2026 at 11:30 UT is: N05W12, (196", 1") 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 21 Jul '26

21 Jul '26

Dear Collaborators, Solar activity has slightly increased. Several flares were produced since the last message, the largest being an M3.4 from newly numbered active region NOAA 14493 at 22:15 UT yesterday. NOAA 14493 is a newly emerged beta-gamma-delta type region showing significant signs of sunspot dynamism and has produced all 16 flares of the last 24 hours, including two further low M-class events. Elsewhere, NOAA 14492 has developed into a beta-gamma region but has remained relatively quiet. Due to the rapid emergence, significant development, and continued output of NOAA 14493 we will be preemptively issuing a Major Flare Watch at this time with NOAA 14493 as the target region. Further C and M-class activity is likely with a chance for an isolated >M5.0 event in the next 24-48 hours. The position of NOAA 14493 on 21-July-2026 at 11:30 UT is: N05E02, (-32", 1") 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 20 Jul '26

20 Jul '26

Dear Collaborators, Solar activity remains low. A small number of flares were produced since the last message, the largest being a C2.0 from an unnumbered active region toward the disk centre (slightly above the listed position of NOAA 14491) at 09:06 UT today. Newly numbered active region 14492 has rotated over the northeastern limb and is likely associated with the recent flaring activity in this region over the previous days. Currently, an accurate determination of the complexity and size of NOAA 14492 requires the region to rotate further onto the disk, however the region shows notable signs of emerging flux. For now, NOAA 14492 will be the target region and should be monitored for further activity. Additional C-class events are expected. The position of NOAA 14492 on 20-July-2026 at 11:30 UT is: N15E66, (-834", 212") 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

19 Jul '26

Dear Collaborators, Solar activity remains at a very low level. A small number of flares were produced since the last message, the largest being an occulted C1.6 at 15:40 UT yesterday. The active region beyond the northeastern limb was the source region for all of the flares in the last 24 hours. The target region will remain at the northeastern limb around the site of the occulted flare. Further C-class activity is expected. The approximate position of the target region on 19-July-2026 at 07:30 UT is: N24E90, (-862", 383") 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 very low level. A small number of flares were produced since the last message, the largest being a C2.3 from NOAA 14489 at 03:56 UT today. Additionally, a C2.3 and further B-class flares were produced from an active region currently beyond the northeastern limb. NOAA 14489 has shown a change in complexity and signs of potential further activity and should be monitored. However, the target region will switch to the northeastern limb around the site of the cluster of C- and B-class flares. Additional low C-class activity is anticipated. The approximate position of the target region on 18-July-2026 at 07:30 UT is: N15E87, (-910", -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 turned back to a low level since the last message. The largest event in the period was a C5.3 flare at 21:19 UT yesterday (7/16) from the target region located on the Southeast limb. A small sunspot rotated from the Southeast limb (S11E54) was assigned the number, NOAA 14491, but the recent flare activities appear to have come from the plage region extending close to the limb. In the next 24 hours, we will continue to monitor this plage region on the Southeast limb, expecting additional C-class events with eruption. The position of the target 17-July-2026 at 16:00 UT is: S11E83 (-918", -200") 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 increasing due to the activities from the region located behind the Southeast limb, with the largest being a C8.9 eruptive flare at 20:46 UT yesterday (a link to the movie of this event shown below). This region appears to be the source of the C3.9 flare on 7/14, as well as 3 low-to-mid C class flares reported in the last 24 hours. Yesterday's target, NOAA 14489 produced a C1.5 flare at 18:03 UT yesterday (7/15), but has quietened since then. https://www.lmsal.com/solarsoft/archive/sdo/media/ssw/ssw_client/data/ssw_s… Today, we will switch the target to the Southeast limb region yet unnumbered to monitor the additional flares of a high-C class. The position of the target 16-July-2026 at 15:00 UT is: S09E83 (-923", -171").

Dear Collaborators, Solar activity remains low since the last message. The largest event in the period was a C3.3 flare at 8:31 UT today (7/15) produced by NOAA 14489. There were two other C class events (C1.2 at 2:38 UT and C1.1 at 4:37 UT), both came from behind the limb. The former was an eruptive event from NOAA 14485 now located behind the SouthWest limb, while the latter was from the region that produced a C3.9 flare yesterday, being still behind the SouthEast limb. The target region NOAA 14482 reduced its sunspot area, only produced a B class event. Today, we will switch the target to NOAA 14489, at the Northeast side of the sunspot, where the C3.3 flare initiated. The position of the target in NOAA 14489 on 15-July-2026 at 15:00 UT is: S06E45 (-674", -151").

Dear Collaborators, Solar activity continued to be at a low level since the last message. The largest event in the period was a C3.9 flare at 12:18 UT today (7/14) from the region behind the Southeast limb. The region rotated from the Southeast limb yesterday was assigned the number as NOAA 14489, but the flare activity of this region has somewhat settled for the last 12 hours. The target region, NOAA 14482 produced a C1.5 flare at 9:49 UT today, which is the second largest event in the period. The EUV loops emanated from its sunspot are persistently connected with the nearby plage regions and with NOAA 14487, a Northern neighboring region. Today we will continue to observe the umbra of NOAA 14482, expecting additional C class events. The position of the target in NOAA 14482 on 14-July-2026 at 15:30 UT is: S09W52 (738", -192").

Dear Collaborators, Solar activity has reduced to a low level since the last message. The largest event in the period was a C1.2 flare at 22:48 UT yesterday (7/12) from the Southwest limb over the target region, NOAA 14485. This region has been the main source of flares in the past 24 hours but will be out of our view in the next 24 hours. A unipolar region rotated from the Southeast limb is showing minor activity (2 B class flares) since yesterday, but it is not clear yet whether the activity persits. NOAA 14482 holds the largest sunspot on the disk, from which some EUV loops extend to the North neighboring region, NOAA 14487. Although currently no flare is reported from this region, some interacting activity with 14487 is expected. Today we will observe NOAA 14482 as a new default target, expecting the activity of C class. The position of the target in NOAA 14482 on 13-July-2026 at 16:30 UT is: S08W39 (592", -187").
