Dear Collaborators,
Solar activity has remained low. The largest event since the last message was a C9.5 flare at 19:43 UT yesterday, attributed a newly emerged region NOAA 14353 (N17E03, beta/D-type). However, flares from other regions (e.g., the target NOAA 14345) also contributed to the soft X-ray flux. NOAA 14341 (S11W42, beta/C-type) and the target region NOAA 14345 (S17W35, beta- gamma/E-type) produced a number of low C-class flares during the period. Today, we will continue monitoring NOAA 14345, with particular attention to its leading sunspot. Additional C-class activity is expected over the next 24 hours, with a chance of an isolated low M-class event.
The position of NOAA 14345 on 23-Jan-2026 12:30 UT is:
S17W35 (536",-213")
