Dear Collaborators,

Solar activity remains at a moderate level in the last 24 hours. The target region NOAA 13932 produced the largest flares in the period - an M1.1 at 04:03 UT today and two C9.6 at 22:58 UT yesterday and at 10:21 UT today. 13932 has emerged additional spots and increased in its spot area to be classified as a beta/E-type sunspot group. To the North West of 13932, NOAAs 13928 (beta/D-type, S14E27) and 13933 (beta/D-type, S08E27) also produced four >C5 flares. Today the target shall continue as 13932, and please also include NOAAs 13928 and 13933 in the field of view if possible. Note that another active region NOAA 13930 (beta/C-type, S22W56) also was the source of three >C5 flares. Further C-class activity is expected, with a good chance for another low-M flare in the following 24-hour period.

The position of NOAA 13932 on 22-Dec-2024 at 12:30 UT is:

S17E47 (-683", -264")
