Dear Collaborators,

Solar activity is at a moderate level. Target region NOAA 13388 has been stable since the last message, remaining classified as a beta/C-type sunspot group. Old region NOAA 13376 produced the largest magnitude flare in the period from beyond the North West limb (an M4.1 on 28-Jul-2023 at 15:39 UT), but is now completely out of view. Newly numbered region NOAA 13390 (an alpha/H-type) has already produced four mid-to-high C-class events, with the largest being a C9.2 flare on 29-Jul-2023 at 10:18 UT. Further C-class flares are expected in the next 24-hour period, with a chance for a low M-class flare.

The position of NOAA 13390 on 29-Jul-2023 at 13:00 UT is:

S18E63 , ( -801", -331" )
