Dear Collaborators,

Solar activity is at a moderate level. The largest event since the last
message was an M4.0 flare at 20:01 UT yesterday from the target region
NOAA 13435 (N09E38). 13435 has increased in magnetic complexity
and been classified as a beta-delta/D-type sunspot group. It also produced
three C-class flares during the period, including a C9.7 and two C3 flares.
This region shall continue as the target region. If possible, please also
include NOAA 13438 (N10E30) nearby in the field of view, which produced
a low-C flare in the period and has been classified as a beta-gamma/D-type
configuration. Additionally, NOAA 13436 (N20W53) remained active and
has been designated as a beta-gamma/D-type configuration, which also
produced five low-C flares in the period. Further C-class flares are expected
over the next 24 hours, with a good chance for more M-class flares.

The position of NOAA 13435 on 20-Sep-2023 at 07:30 UT is:

N09E38 (-582" , 56")
