Dear Collaborators,
Solar activity has been at a moderate level since the last message. The target limb region has been numbered as NOAA 13917 with a beta/C-type configuration. It produced two low M-class flares, an M1.4 (being the largest one) at 20:57 UT yesterday and an M1.0 at 06:56 UT today, plus four C-class flares. Also note that NOAA 13916 (S16E53, beta/C-type) and 13906 (S17W91, beta-gamma/E-type) also produced an M1.3 and an M1.1 flares, respectively. Additional M-class activities are very likely in the following 24 hours.
The position of NOAA 13917 on December 5 at 08:30 UT is: S09E56 (-798", -155")
