MM#009 Default Target
by Max Millennium Chief Observer 04 Oct '26

04 Oct '26

Dear Collaborators, Solar activity has been at a low level. The largest event in the period was a B9.3 flare at 6:21 UT today (10/4) produced by NOAA 14546 in the Southwest quadrant. This event is very compact and the region is reducing the area as it approaches the limb. The target region, NOAA 14545 produced 3 mid-B class events in the period, the largest being a B4.9 at 23:59 UT yesterday. NOAA 14545 maintains its spots surrounded by a larger plage. Today the target continues to be NOAA 14545, at the area of trailing sunspots. The activities of low-C class are expected. The position of the target in NOAA 14545 on 4-October-2026 at 16:00 UT is: N20E25 (-394", 234").

Dear Collaborators, Solar activity remains very low. GOES X-ray (1-8A) background stays at a B2 level, the largest event reported in the period was a B5.0 at 14:59 UT today (10/3) from the target region, NOAA 14545. NOAA 14545 maintains the magnetic complexity of a bata type, with new flux emergence at the area of trailing sunspots. Today we will continue to observe NOAA 14545, expecting low-C class events from the area of trailing spots. The position of the target in NOAA 14545 on 3-October-2026 at 16:00 UT is: N19E38 (-568", 240").

Dear Collaborators, Solar activity continues to be at a very low level. The largest event in the period was a C1.5 flare at 21:20 UT yesterday (10/1) from the Northeast limb region, mentioned yesterday and now assigned the number NOAA 14545, classified as a beta type. The target region, NOAA 14535 produced only a few low-B class events and will undergo its limb transit in the next 24 hours. Today we will switch the target to NOAA 14545 to observe the area of its trailing sunspot where the C1.5 flare was produced. Additional activity of low-C class is expected. The position of the target in NOAA 14545 on 2-October-2026 at 16:00 UT is: N20E54 (-725", 277").

Dear Collaborators, Solar activity has been very low since the last message. The largest event in the period was a B7.8 at 12:41 UT today (10/1). Two regions appear to have contributed to this event, one is NOAA 14535 at a plage in the North of the sunspot, the other is a plage close to the Northeast limb at the latitude ~20 degree North. The latter region holds tiny sunspots and is the source of a B5.0 event at 2:26 UT. Today we will continue to observe NOAA 14535, but the target will be a plage in the North of the main sunspot. High-B to low-C class events are expected. The position of the target in NOAA 14535 on 1-October-2026 at 16:00 UT is: N14W64 (838", 186").

Dear Collaborators, Solar activity has been at a low level since the last message. The target region, NOAA 14535 produced a C8.6 flare at 2:30 UT today (9/30), which is the largest event in the period, but somewhat settled since then. There are a number of high-B to low-C class activities reported from behind the East limb at the latitude ~10 degree North. The EUV loops above this area show rapid variation, but currently we only see a plage close to the Northeast limb. Today the target remains at NOAA 14535, on the area of polarity inversion, expecting additional C class events. The position of the target in NOAA 14535 on 30-September-2026 at 16:00 UT is: N11W52 (745", 127").

Dear Collaborators, Solar activity has slightly increased but still been at a low level. The largest event since the last message was a C2.5 flare at 15:05 UT yesterday (9/28) from the West limb produced by NOAA 14536. This region additionally produced two C1 class and a few B class flares, but now has completely rotated behind the limb. A few near-C class events were reported from the Northeast limb but the attributed region is not visible yet from us. Yesterday's target, NOAA 14535 reduced its area, showing only B class activity, but was re-classified as a beta-gamma type. Today NOAA 14535 remains the target, expecting high-B to low-C activities. The position of the target in NOAA 14535 on 29-September-2026 at 16:00 UT is: N11W39 (601", 98").

Dear Collaborators, Solar activity continues to be low since the last message. Two low-C class flares (C1.2 at 15:54 UT and C1.3 at 18.58 UT both on yesterday, 9/27) were reported from NOAA 14535 located at N11W15. A cluster of active regions (NOAA 14534, 14536 and 14538) produced several B-class flares but has almost moved out of the view from Earth. NOAA 14535 is currently the region with the highest magnetic concentration on the disk, although showing no flare activity during the recent 20 hours. Today we will switch the default target to NOAA 14535 and observe the area of its polarity inversion. Activities of low-C class are expected. The position of the target in NOAA 14535 on 28-September-2026 at 16:00 UT is: N11W26 (423", 85").

Dear Collaborators, Solar activity is at a low level. Several flares have been produced since the last message, the largest being a C3.1 from NOAA 14534 at 16:50 UT yesterday. The target region cluster is transiting the northwestern limb with some extremities of the constituent regions remaining in view. Meanwhile, NOAA 14536 has developed into a beta-gamma region but is yet to produce significant activity. NOAA 14534 and the surrounding ARs will remain the target region for what may be the final 24 hours before moving out of view entirely. Further B-class and low C-class activity is expected. The approximate position of NOAA 14534 on 27-Sep-2026 at 00:30 UT is: N10W90, (945", 167") 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 continues at a low level. A small number of flares were produced since the last message, the largest being a C1.2 from NOAA 14534 at 18:20 UT yesterday. This region and the surrounding cluster are now positioned on the northwestern limb and will begin to transit out of view in the next 24-48 hours as they further progress. Elsewhere on the disk there is little activity. NOAA 145434 will continue as the target region as it remains in view, further low C-class activity and B-class activity is likely. The approximate position of NOAA 14534 on 26-Sep-2026 at 00:30 UT is: N10W76, (920", 167") 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 low. A small number of flares were produced since the last message, the largest being a C1.5 from NOAA 14535 at 08:52 UT today. The clustered target region is now progressing onto the northwestern limb and will transit beyond view within the next few days. The region still shows some activity, however NOAA 14536 has produced the most flares in the last 24 hours and has developed into a beta-delta type region. This region is within reasonable proximity to the NOAA 14534 and the surrounding regions. The cluster about NOAA 14534 will remain as the target region for now, however attention should also be paid to NOAA 15436 over the next 24 hours. Further B-class and low C-class activity is expected. The approximate position of NOAA 14534 on 25-Sep-2026 at 00:30 UT is: N12W61, (836", 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.
