Dear Collaborators,

Solar activity has increased to an intermediate level since the 
last message. The largest event was a C6.6 flare at 21:04 UT 
yesterday from a region between NOAAs 14224 (beta-gamma/D-type, 
S13W15) and 14223 (alpha/A-type, S17W14). To the east of 
14223, NOAA 14217 produced six low-C flares, with its largest 
being a C2.7 at 21:27 UT yesterday. 14217 retains a beta/E-type 
sunspot group, with the emergence of new spots. Today, the 
target shall switch to NOAA 14217. Yesterday’s target, NOAA 
14220 (beta-gamma/E-type, S18W62) was merely the source of 
a C2.3 flare at 17:01 UT yesterday. Additional low-C activity is 
expected in the following 24 hours.

The position of NOAA 14217 on 22-Sep-2025 at 11:30 UT is:

S17W26 (402", -379")
