Dear Collaborators,
Solar activity has been at a moderate-to-low level since the last message. The largest event of the period was an M2.5 flare at 10:32 UT yesterday produced by NOAA 13906, which has been rotated over the west limb. 13906 was also the source of six low C-class flares yesterday. The target region NOAA 13917 has been designated as a beta-gamma/ D-type configuration and produced six C-class flares during the period. Also note that a nearby region NOAA 13916 (S16E37) produced a C8.0 flare at 06:42 UT today and was also designated as a beta-gamma/D-type configuration. Further C-class activities are expected with low M-class flares probable in the next 24 hours.
The position of NOAA 13917 on December 6 at 08:30 UT is: S08E46 (-695", -137")
