Dear Collaborators,
Solar activity has declined to a low level since the last message. The largest event in the past 24 hours was a C3.7 flare at 6:36 UT today(10/21) from behind the Northeast limb. Yesterday's target, NOAA 14248 on the West limb produced 3 low-C class flares but the loop system is going out of our view today.
There were a few low-C class activities from the Southeast quadrant of the solar disk. NOAA 14257 had two leading (negative polarity) sunspots about 50 arcsec apart in North-South direction. Today the Southern spot was given a new number as NOAA 14262, and this region appears to be involved in the low-C class events at 15:14 UT and 23:33 UT on 10/20. Today, we will observe this region, NOAA 14262 as the default target, expecting additional C class events.
The position of the target in NOAA 14262 on 21-October-2025 at 15:00 UT is: S13E26 (-421", -295").
