Dear Collaborators,

Solar activity continues at low levels. The largest event since the last message was a C2.7 flare at 05:18 UT on 05-Dec-2022 produced by a newly numbered region NOAA 13158 (N24W01) that has a beta/C-type configuration. 13158 was productive with other two ~C1 and two ~B8 flares during the period. NOAA 13155 (N23W32, beta/D-type) continued producing low C-class and high B-class events. The target region NOAA 13156 produced only a C1.9 event at 12/05/01:40 UT and was classified as a beta/C-type configuration. We shall continue watching 13156 for one more day but also include NOAA 13157 (N16E54, beta/D-type) in your field of view if possible. Please also note that NOAA 13153 (S17E26) produced four ~C1 flares, which has a beta/F-type sunspot group with increasing the sunspot area and number of spots. Further C-class activities are expected from various regions only with a slight chance for a low M-class flare in the following 24-hour period.

The position of NOAA 13156 on 05-Dec-2022 at 12:30 UT is:

N25E32 (-469", 408")
