Dear Collaborators,
Solar activity has been at moderate levels for the past 24 hours. The largest event since the last message was an M2.2 flare at 11:32 UT today from a northeast limb region (unnumbered yet). This region has also produced four M1 and multiple C-class flares. Today the Major Flare Watch region will switch to this limb region because of its recent higher frequency of flaring. Yesterday’s target was numbered as NOAA 13310 (beta/D-type, S20E67) and only produced 2 low C-class flares. Another region NOAA 13305 also produced a C-class flare. Further low M-class activities are very likely over the following 24-hour period, with a chance for an above M5 flare.
The approximate position of the target on 18-May-2023 at 11:30 UT
N18E88 (-880", 290")
