Dear Collaborators,
Solar activity has continued at a moderate level since the last message. The largest events in the period were two M1.0 flares, produced by NOAA 13917 (S08W61) and yesterday's target NOAA 13922 (S18E17), respectively. 13922 produced another two low C-class flares in the period, while 13917 was the most flare-productive region on the disk, which produced another 11 C-class flares in the period. 13917 retains a beta- gamma-delta configuration. Today, the target region shall switch to NOAA 13917 due to its activity history and magnetic complexity. Further C-class and additional low M-class flares are expected in the next 24 hours.
The position of NOAA 13917 on December 14 at 08:30 UT is:
S08W61 (845",-128")
