Dear Collaborators,

Solar activity is at a low level. Target region NOAA 13450 has continued to decay since the last message, decreasing slightly in spot area and magnetic classification to be designated as a beta/E-type group. This region produced just one C-class flare in the period, while most of the remaining flares came from the close pair of NOAA regions 13451 (a beta/D-type group with five C-class flares) and 13452 (a beta/E-type group, with one C-class flare). The target switches to 13451 which is the smaller spot group, but produced the largest magnitude flare (a C3.8 flare on 5-Oct-2023 at 06:51 UT). Interested observers should try to include 13452 in their field-of-view as well if possible. More C-class flares are expected in the following 24-hour period.

The position of NOAA 13451 on 5-Oct-2023 at 18:00 UT is:

N12W02 , ( 32", 92" )
