Dear Collaborators,

Solar activity has reached a high level for the past 24 hours.
A southeast limb region (unnumbered yet) is the most flare-
productive and has produced 8 C-class flares as well as the
largest event in the period - an M9.6 flare at 16:31 UT on
16-May-2023. At this point, we are implementing a Major Flare
Watch on this limb region. Yesterday’s target NOAA 13305
(beta/D-type, N09W23) was the source of only four C1 flares
with signs of decay. Further C-class activities are expected
over the following 24-hour period, with a chance for another
above M5 flare.

The approximate position of the target on 17-May-2023 at 11:30 UT

S18E88 (-875", -350")
