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").
