MM#009 Default Target
by Max Millennium Chief Observer 19 Jul '26

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").

Dear Collaborators, Solar activity has increased to a low-to-moderate level since the last message. The target region, NOAA 14485 produced an M1.2 flare at 7:17 UT today (7/11) in addition to 3 C class flares in the last 24 hours. NOAA 14482 is the current largest region on the disk, but keeps flare-quiet for a few days. The flares from NOAA 14485 are initiated from the area of its leading sunspots, although it becomes harder to see due to the proximity to the limb. Today, we will continue to observe NOAA 14485, as it progresses over the Southwest limb. Additional C class to low-M class events are expected. The position of the target in NOAA 14485 on 12-July-2026 at 15:30 UT is: S09W78 (912", -171").

Dear Collaborators, Solar activity continues to be low since the last message. The largest event in the past 24 hours was a C6.0 flare at 14:33 UT yesterday (7/10) produced by NOAA 14485. This region is the only source of the reported flares in the last 24 hours, while the target region, NOAA 14482 has been flare-quiet for more than 48 hours. Today, we will switch the target to NOAA 14485 and observe the East side of the Southern preceding sunspot, the site of the C6.0 flare. Additional C class activities are expected with a slight chance of low-M class event. The position of the target in NOAA 14485 on 11-July-2026 at 15:30 UT is: S10W63 (826", -208").

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 B7.5 from NOAA 14485 at 05:02 UT today. NOAA 14482 has reduced in complexity and is now classified as a beta-gamma type region. NOAA 14485 also remains classified as a beta-gamma. There was no activity >B-class in the last 24 hours. Further B-class and low C-class activity is likely. The position of NOAA 14482 on 10-July-2026 at 11:30 UT is: S09E08, (-130", -210") 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.
