MM#009 Default Target
by Max Millennium Chief Observer 12 Aug '26

12 Aug '26

Dear Collaborators, Solar activity has remained at a low level in the last 24 hours. The largest event during this period was a C2.5 flare at 22:55 UT yesterday, originating from the newly emerged active region NOAA 14507. This region was also the source of a C1.7 plus five mid-B flares. It has been classified as a beta/C-type magnetic configuration. Yesterday’s target, NOAA 14505, has completely rotated out of Earth view. Today, the target shall switch to 14507 from 14505. In addition, NOAA 14508 (N06E63, alpha/H-type) contributed several flares below C1.7. Further B-class activity is expected, with additional low-C flares likely within the coming 24 hours. The position of NOAA 14507 on 12-Aug-2026 11:30 UT is: N04E36 (-556", -20") 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 grown to a ~C2 level over the past 24 hours. The target region NOAA 14505 produced the largest event, a C2.4 flare at 12:34 UT yesterday. Additionally, this region also generated a C1.0 and two mid-B flares. 14505 was designated as a beta/D-type magnetic configuration, as it transited beyond the northwest limb. Today, the target will remain with the looptops of NOAA 14505. B-class and low-C activities are probable in the next 24 hours. The position of NOAA 14505 on 11-Aug-2026 11:30 UT is: N15W91 (913", 245") 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 level of solar activity has increased since the last message. The largest event was a C1.8 flare at 16:30 UT yesterday from the newly emerged active region NOAA 14505. This region has been the most productive, producing four ~C1 and eight mid-to-high B-class flares. It has been classified as a beta/B-type sunspot group. Today, 14505 becomes the new target. B-class activity is expected, with additional low-C flares likely over the following 24 hours. The position of NOAA 14505 on 10-Aug-2026 11:30 UT is: N16W86 (907", 252") 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 slightly increased since the last message, but still at a low level. The largest event in the period was a B4.9 flare at 3:23 UT today (8/9) contributed by two regions, NOAA 14498 and 14502, both located on the West limb. Although these regions repeated mid-B class events in the last 12 hours, they are being out of Earth's view in the coming 24 hours. Yesterday's target, NOAA 14504 only produced a B4.2 event at 00:13 UT today. The patches of its plage are getting thinner but maintain some magnetic complexity. In the next 24 hours, we will continue to observe the Easternmost plage of NOAA 14504, expecting additional B-class events. The position of the target in NOAA 14504 on 9-August-2026 at 15:30 UT is: S22E25 (-372", -442").

Dear Collaborators, Solar activity has been very low since the last message. Yesterday's target, a small emerging region in the East of NOAA 14503 was assigned a number, NOAA 14504. This region produced several B-class events, including a B7.6 at 08:48 UT today(8/8) which was the largest event in the period. There is no other source of flare activities in the last 24 hours. Today we will continue to observe NOAA 14504, on the East side of the plage at the boundary of the positive and negative polarities. Additional B-class events are expected. The position of the target on 8-August-2026 at 15:00 UT is: S21E39 (-555", -421").

Dear Collaborators, Solar activity continues to be at a low level since the last message. The largest event in the past 24 hours was a C1.0 flare at 19:21 UT yesterday (8/6) from a newly emerged region in the East of NOAA 14503. This region consists of several tiny pores and surrounding plage, thus yet unnumbered. There was an eruptive event from behind the East limb at ~5 degrees South, which is the main contributor of a few hours of hump in GOES X-ray flux starting around 6UT today (see the SSW movie link below) . www.lmsal.com/solarsoft/archive/sdo/media/ssw/ssw_client/data/ssw_service_2… Yesterday's target, NOAA 14498 only produced a B5.6 flare at 18:10 UT, while a few low-B class events were reported from its adjacent region NOAA 14500. Both regions lost sunspot area and magnetic complexity. Today we will switch the default target to an unnumbered region from the Southeast limb, the source of a C1.0 flare yesterday. We will observe the East side of the plage with positive polarity associated with the pores of negative polarity. High-B to low-C class events are expected. The position of the target on 7-August-2026 at 16:00 UT is: S21E51 (-689", -402").

Dear Collaborators, Solar activity remains low since the last message. The largest event in the past 24 hours was a B9.2 flare at 15:22 UT yesterday (8/5) from NOAA 14498. Yesterday's target, NOAA 14502 produced two mid-B class flares, while it slightly decreased sunspot area. NOAA 14498 and its adjacent active region, NOAA 14500 share a bright plage with a dark flament between them. In addition to the B9.2 flare from 14498, NOAA 14500 also produced a B5.4 flare at 8:40 UT today. Although these flares are minor, hot EUV loops are brighter over these two regions than those in NOAA 14502. Therefore we will switch the default target back to NOAA 14498 to observe the activities from these combined regions. The target will be on the South side of the main sunspot of 14498, expecting additional B-class events or larger and a filament activity. The position of the target in NOAA 14498 on 6-August-2026 at 16:00 UT is: N13W51 (722", 154").

Dear Collaborators, Solar activity has slightly increased after the message yesterday, but has come back to a low level for the lastest several hours. The largest event in the past 24 hours was a C1.7 flare at 05:56 UT today (8/5) from NOAA 14502 located in the Southwest quadrant. A small region rotated from the Southeast limb, mentioned yesterday was registered as NOAA 14503, but only produced a minor flare below C class. The target region, NOAA 14498 lost its area and magnetic complexity, only showed minor activity since yesterday. Today we will switch the default target to NOAA 14502 to observe its following sunspot. We will look at the area where the C1.7 flare was initiated, expecting additional C class events. The position of the target in NOAA 14502 on 5-August-2026 at 16:00 UT is: S06W31 (495", -185").

Dear Collaborators, Solar activity continues to be very low since the last message. The largest event in the past 24 hours was a C1.2 flare at 11:52 UT today (8/4) from a small region rotated from the Southeast limb at ~18 degrees earlier today. This region appears to be accompanied by a tiny sunspot and produced another low-C class flare at 14:15 UT. However, it is still uncertain whether this region will grow further. The target region, NOAA 14498 only produced a high-B class event in the past 24 hours. This region is showing signs of decay, but remains to be the most magnetically complex region on the disk. Therefore we will continue to observe NOAA 14498 in the next 24 hours, at the small sunspot in the Southeast of the main sunspot, expecting the activities of low-C class. The position of the target in NOAA 14498 on 4-August-2026 at 16:00 UT is: N13W23 (369", 131").

Dear Collaborators, Solar activity has been very low since the last message. The largest event in the past 24 hours was a C1.4 flare at 11:28 UT today (8/3) from the target region, NOAA 14498. This region was slightly reduced in size but maintains its magnetic complexity of a beta-delta type. Today, we will continue to observe NOAA 14498 on the small sunspot with mixed polarity, that is located in the Southeast of the main (positive polarity) sunspot. Additional C class events are expected. The position of the target in NOAA 14498 on 3-August-2026 at 15:30 UT is: N12W09 (159", 117").
