MM#009 Default Target
by Max Millennium Chief Observer 13 Jul '26

13 Jul '26

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.

Dear Collaborators, Solar activity remains at a low level. Several flares were produced since the last message, the largest being an M1.5 from NOAA 14482 at 17:49 UT yesterday. NOAA 14482 has now developed into a beta-gamma-delta region with an approximate size of 420 μh. Sunspot activity levels from this region have been moderate. Currently, NOAA 14482 does not meet the criteria for a definitive Major Flare Watch, however this region should be monitored closely for larger M-class activity in the next 24 hours. Additionally, NOAA 14485 has declined into a beta-gamma region and may provide further activity. Sustained C-class activity is likely with further isolated M-class events. The position of NOAA 14482 on 09-July-2026 at 11:30 UT is: S09E20, (-319", -205") 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 low level. Several flares were produced since the last message, the largest being an M4.0 from NOAA 14482 at 14:09 UT yesterday. NOAA 14482 continues to show an increase in sunspot area and elements of dynamism, however it remains classified as a beta-gamma type region. NOAA 14482 will continue as the target region, further C-class activity is expected with the chance for additional isolated M-class events. The position of NOAA 14482 on 08-July-2026 at 11:30 UT is: S09E33, (-509", -197") 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 reduced since the last message. A small number of flares were produced since the last message, the largest being an occulted C3.8 from NOAA 14479 at 18:25 UT yesterday. NOAA 14479 is now well beyond the solar limb. NOAA 14482 has developed into a beta-gamma type region and grown in size, while showing strong emerging flux. At this time, we are ending the Major Flare Watch. The target region will switch to NOAA 14482. Further C-class activity is expected with the chance for isolated low M-class events. The position of NOAA 14482 on 07-July-2026 at 11:30 UT is: S09E47, (-683", -187") 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 06 Jul '26

06 Jul '26

Dear Collaborators, Solar activity remains at a high level. NOAA 14479 produced numerous flares in the last 24 hours, the largest being an M5.3 at 17:51 UT yesterday. This region has passed beyond the northwestern limb, however it may still provide further >=M class activity from its occulted position. NOAA 14482 has not produced any significant further activity since the X-class event on 04/07/26, however this region still shows significant emerging flux and should be monitored closely. The Major Flare Watch will remain active for what may be a final 24 hours while we have the potential for further significant occulted emission from NOAA 14479 and further activity from NOAA 14482 (S08E55) . The position of NOAA 14479 on 06-July-2026 at 11:30 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 05 Jul '26

05 Jul '26

Dear Collaborators, Solar activity has been at a high level. The target region NOAA 14479 was the source of 11 low M-class plus 6 C-class flares over the past 24 hours, the largest ones being two M3.2 flares. Please note that the largest flare during the period was an X1.1 flare at 07/04/20:29 UT produced by a newly numbered region NOAA 14482 (S08E75), which is still at the southeast limb. Today we will continue to watch NOAA 14479 for a final 24 hours as it is rotating over the west limb. Low M-class activities are expected with a good chance of major flares from NOAA 14479 and 14482 in the following 24 hours. The position of NOAA 14479 on July 5 at 03:30 UT is: N16W81 (896", 251") See http://www.SolarMonitor.org <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 '26

04 Jul '26

Dear Collaborators, Solar activity has been at a moderate to high level. The largest event since the last message was an M6.7 flare at 07/03/17:49 UT produced by the target region NOAA 14479. 14479 was also the source of six low M-class flares plus seven C-class flares. Please note that another region NOAA 14478 (S06W48, downgraded to a beta-gamma/F-type configuration) produced the second largest flare, an M6.3 flare at 07/03/18:57 UT. Today we continue to watch NOAA 14479 which has a beta-gamma-delta/F-type sunspot group. Further low M-class activities are expected with a chance of some major flare in the following days. The position of NOAA 14479 on July 4 at 03:30 UT is: N17W68 (837", 257") See http://www.SolarMonitor.org <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.
