Dear Collaborators,

Solar activity has returned to a moderate level. The largest event since the last message was an M1.6 flare at 15:42 UT yesterday (11/22), produced by the target region NOAA 13905 (S09E59). This region has increased in magnetic complexity to a beta-gamma type and produced another four C-class flares in the period. NOAA 13905 will remain the target today, as it is showing mixed polarities in the intermediate portion. Please note that NOAA 13906 (S16E68, beta/D-type), located near the target region, produced an M1.1 flare and three C-class flares in the period. If possible, please also include 13906 in your field of view. Further low M-class flares are expected in the next 24-hour period.

The position of NOAA 13905 on 23-Nov-2024 at 08:30 UT is:

S09E59 (-824",-167")
