Dear Collaborators,

Solar activity has returned to low levels. The largest event since the last message was a C3.1 flare at 16:12 UT on 31-Jan-2023 produced by the target region NOAA 13207. This region was still the most productive and has produced 10 low C-class flares, remaining a beta/C-type sunspot group. Today the target shall still be this region. Moreover, some other active regions (NOAA 13206, 13204) also produced a few low-level events over the period. Further C-class activities are expected in the next 24 hours.

The position of NOAA 13207 on 2-Feb-2023 12:30 UT

S11E58 (-812", -131")
