Dear Collaborators,
Solar activity has increased to a moderate level since the last message. Two M class flares were reported in tandem yesterday (12/6) both from NOAA 14299, which is the region that produced an X flare on 12/1. While first event, an M1.2 at 18:58 UT was started from the Eastern (larger) sunspot, an M8.1 at 20:29 UT occured from the Western (smaller) sunspot with accompanying a filament eruption. While this region has been in the process of flucturing, the Western sunspots are losing their penumbra after the M8 event.
The target region, NOAA 14294 has produced 8 C class flares during the recent 10 hours. The largest event from this region was a C7.5 at 11:51 UT today from the Southeastern portion of its trailing (the largest) sunspot. An emergence of new flux with an opposite polarity to the sunspot is observed in this area.
Today we will continue to observe NOAA 14294, but the pointing is moved to the area of the C7.5 event, expecting additional high-C class events or larger.
The position of the target in NOAA 14294 on 7-December-2025 at 17:00 UT is: S18W21 (337", -310").
