Dear Collaborators,

Solar activity has been at an intermediate level since yesterday's M1.0 flare. The largest event since the last message was a C8.1 flare at 09:09 UT on 02-Dec-2022 produced by an unnumbered limb region (N16E81). Yesterday's target region NOAA 13152 produced only a C1.0 event. The recently emerged NOAA 13154 (S38W12) has been classified as a beta/D-type sunspot group. NOAA 13155 (N22E12) was less productive, which was classified as a beta/B-type region. NOAA 13153 was productive with 6 C-class and 2 B-class flares, which was classified as a beta/D-type configuration. The target region shall switch back to NOAA 13153 because of its recent higher frequency of flaring activity and increased magnetic complexity. Further high C-class activities are probable with a chance for an M-class flare in the following 24-hour period.
