Dear Collaborators,

The level of solar activity is moderate. Yesterday's target
NOAA 13435 (N09W04, beta/D-type) only produced one
C7.3 flare in the period while NOAA 13443 (N28W47) was
the source of three M1 flares, the largest of which was an
M1.9 on 22-Sep-2023 at 22:25 UT. The Major Flare Watch
shall remain in effect, but the target shall switch from NOAA
13435 to NOAA 13443. The new target is classified as a
beta-gamma region and continues to develop due to flux
emergence in its edges. Please note that NOAA 13445
(S15E26, beta/D-type) also produced eight C-class flares
in the period, and NOAA 13437 (S18W76, beta/D-type)
produced a C9.9 flare on 22-Sep-2023 at 19:20 UT. Low
M-class activities are still expected over the following 24 hours,
with a slight chance of an above M5 flare.

The position of NOAA 13443 on 23-Sep-2023 at 11:30 UT is:

N28W47 (618" , 375")
