Dear Collaborators,

Solar activity has returned to a moderate level. The largest event since the last message was an M1.2 flare at 19:11 UT yesterday (11/20), produced by NOAA 13889, which has completely rotated over the west limb. The regions NOAA 13892 and 13897, which have also rotated over the west limb, were the sources of several C-class flares. The target region NOAA 13901 (S07E28) retains a beta-gamma magnetic configuration and produced three C-class flares in the period. At this time, we are ending the Major Flare Watch, but NOAA 13901 shall remain the target region as it is emerging new magnetic flux in its trailing portion. Further C-class activity is expected, with a chance of low M-class flares in the next 24 hours.

The position of NOAA 13901 on 21-Nov-2024 at 12:30 UT is:

S07E28 (-454",-149")
