Dear Collaborators,

Solar activity has returned to a moderate level since the last message. The target region NOAA 13511 continued to be the most flare-productive spot region, being the source of more than ten C-class flares as well as the largest magnitude event in the period - an M2.3 at 03:42 UT today. 13511 has now developed to a beta-gamma region with fresh flux emergence and shall continue as the target region. The Major Flare Watch will be extended for a further 24 hours, with a slight chance of an above M5 flare.

The position of NOAA 13511 on 10-Dec-2023 at 12:30 UT is:

S22W66, (826",-363")
