Solar activity continues to be at a low level since the last message.
The largest event in the past 24 hours was a C1.0 flare at 19:21 UT
yesterday (8/6) from a newly emerged region in the East of NOAA 14503.
This region consists of several tiny pores and surrounding plage, thus
yet unnumbered. There was an eruptive event from behind the East limb
at ~5 degrees South, which is the main contributor of a few hours of
hump in GOES X-ray flux starting around 6UT today (see the SSW movie
link below) .

while a few low-B class events were reported from its adjacent region
NOAA 14500. Both regions lost sunspot area and magnetic complexity.
Today we will switch the default target to an unnumbered region from
the Southeast limb, the source of a C1.0 flare yesterday. We will
observe the East side of the plage with positive polarity associated
with the pores of negative polarity. High-B to low-C class events are
expected.
The position of the target on 7-August-2026 at 16:00 UT is:
S21E51 (-689", -402").
