Dear Collaborators,

Solar activity is at a high level. The largest event since the last
message is an M8.2 flare at 14:11 UT yesterday from the target
region NOAA 13435, which has retained its beta-delta/D-type
magnetic configuration and shall remain the target region. Moreover,
the nearby region NOAA 13438 (N10E16, beta/C-type) also produced
six low-to-moderate C-class flares in the period. As such we are
implementing a Major Flare Watch campaign at this time. More
C-class flares are expected over the following 24-hour period,
with a good chance of additional M-class activity.

The position of NOAA 13435 on 21-Sep-2023 at 07:30 UT is:

N09E25 (-400" , 42")
