Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13390 has been re-classified as a beta/C-type sunspot group with having rotated further on disk. NOAA 13380 (a beta/D-type) was the source of an M1.4 flare on 29-Jul-2023 at 16:11 UT, but the target region NOAA 13390 produced a double-peaked M-class event where both X-ray peaks reached M1.8 (each flare starting on 30-Jul-2023 at 08:01 UT and 08:18 UT). C-class activity is expected over the following 24 hours, with M-class flares also likely.
The position of NOAA 13390 on 30-Jul-2023 at 13:00 UT is:
S19E51 , ( -695", -362" )
