Dear Collaborators,

Solar activity had been moderately high since the last message.
Yesterday's target NOAA 13513 retains its beta-gamma magnetic
configuration and produced a small number of low C-class flares
in the period, while NOAA 13511 (a beta/E-type) was the source
of three M-class plus more than ten C-class flares, including the
largest in the period - an M5.4 flare at 22:57 UT yesterday. At this
time we are implementing a Major Flare Watch campaign with
NOAA 13511 as the new target region due to the complexity of
the magnetic field connection between it and the nearby active
regions (such as NOAA 13510) and its additional flux emergence.
Further low M-class activities are expected in the following 24-48
hours, with a chance for another above M5 flare.

The position of NOAA 13511 on 9-Dec-2023 at 12:30 UT is:

S22W52, (713",-364")
