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") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
