Dear Collaborators,
Solar activity remains at moderate levels for the past 24 hours. The largest event since the last message was an M3.7 flare at 02:45 UT today produced by NOAA 13213. 13213 also produced three ~M1 flares during the period. It retains a beta-delta/E-type classification and is showing mixed polarities in its intermediate portion. Today the Major Flare Watch region will switch back to NOAA 13213. Yesterday’s target region NOAA 13217 (S10E56, beta/D-type) was the source of an M1.4 flare and ten C-class events. Further low M-class flares are expected, still with a chance of an above M5 flare in the next 24-48 hours.
The position of NOAA 13213 on 10-Feb-2023 12:30 UT
N30W35 (484", 563")
