Dear Collaborators,
Solar activity has been elevated to a high level since the last message. An X1.1 flare was reported at 4:49 UT today(12/8) from NOAA 14298. This region is classified as an alpha-type, but there was a flux emergence in the Northern vicinity since yesterday. At this time, we will implement a Major Flare Watch campaign on NOAA 14298. However, there are other regions that are also worth paying close attention:
NOAA 14299 produced an M2.5 flare at 23:56 UT yesterday around the Western spot that produced an M8 event on 12/6. The Eastern portion of NOAA 14299 also produced an M1.8 flare at 06:40 UT today.
Yesterday's target, NOAA 14294 and its Eastern proximity region, NOAA 14296 are constantly producing flares of low-C to low-M class in the past 24 hours, including an M2.1 at 00:33 UT and an M1.1 at 12:42 UT today both from NOAA 14294. These active regions maintain their large size and high magnetic complexity as a whole.
In the next 24 hours, we will focus on NOAA 14298, the source region of the X class event today, as the target of the Major Flare Watch campaign. The position of the target in NOAA 14298 on 8-December-2025 at 17:30 UT is: S14W60 (817", -244").
