Dear Collaborators,
Solar activity has reached a ~C1 level. The largest event since the last message was a C3.9 flare at 02:31 UT on 3-Feb-2023 produced by the northwest limb region NOAA 13200. Yesterday's target NOAA 13204 and NOAA 13200 are now beyond the western limb. There were 2 high B-class events from NOAA 13207 which remains a beta/C-type sunspot group but increases the sunspot area and number of spots. Today the target will switch back to NOAA 13207, with a possible increase in activity over the coming days.
The position of NOAA 13207 on 3-Feb-2023 12:30 UT
S12E29 (-463", -112")
