Dear Collaborators,
Solar activity remains at low levels. The largest event since the last message was a C2.9 flare at 16:30 UT on 3-Feb-2023 produced by the target region NOAA 13207. This region was the most productive and produced 4 C-class events, with the increasing number of spots. Today the target shall remain this region. Moreover, NOAA 13206 and an unnumbered plage region (S17E56) also produced several low C-class flares over the period. Further C-class activities are expected in the following 24 hours.
The position of NOAA 13207 on 4-Feb-2023 12:30 UT
S12E16 (-263", -102")
