Dear Collaborators,
The level of solar activity is low-to-moderate. Target region NOAA 13445 has become more fragmented since the last message and retained its beta-delta/D-type magnetic configuration. 13445 continued to be the most flare-productive region with being the source of eleven C-class flares, including the largest magnitude event in the period (a C5.7 on 26-Sep-2023 at 04:22 UT). NOAA 13445 shall continue as the target region. Additional C-class flares are expected over the following 24-hour period, with a slight chance of low M-class activities.
The position of NOAA 13445 on 26-Sep-2023 at 07:30 UT is:
S14W13 (209" , -340")
