Dear Collaborators,
Solar activity has remained at a moderate level in the past 24 hours. The largest event was an M1.0 flare at 09:18 UT today, produced by a region between NOAA 14224 and the target region NOAA 14217. 14224 (S13W43) also produced a C6.7 and three low-C flares, although it was downgraded to a beta/C-type magnetic configuration. 14217 also produced three ~C3 flares and remains a beta-gamma/C-type configuration, showing signs of new magnetic flux emergence. Today, the target shall continue as 14217, but if possible, please also include NOAA 14224 in your field of view. Further C-class activity is expected with additional low-M flares probable in the coming 24 hours.
The position of NOAA 14217 on 24-Sep-2025 at 11:30 UT is:
S16W55 (754", -326")
