Solar activity has slightly increased since the last message, but
stays at a low level. The largest event in the last 24 hours was an
M1.7 flare at 8:54 UT today(10/19) from the target region, NOAA 14551.
There were some flux emergence around NOAA 14551; one is in the West
of the following sunspots, which was the source area of the M1.7
event and a few low-C class flares. The other is the SouthWest of
the following sunspot, which produced two low-C class flares today
(at 02:06 UT and 7:07 UT). This region was registered as NOAA 15559,
but now has significantly decayed.
The other source of flare activity is from NOAA 14557, a beta/E type
region that passed the North central meridian yesterday. This region
has steadily grown in size and continues to produce C-class events,
but they are currently at the low-C level.
Today NOAA 14551 remains the target region. We will observe the
West of the following sunspots, expecting additional C to low-M class
activities.
The position of the target in NOAA 14551 on 19-October-2026 at
16:00 UT is: S14W51 (728", -298").
