Solar activity continued to be low after the last message, but for the
recent several hours, the GOES/XRS background has been elevated
to a C3 level due to the new regions; one appeared from the Southeast
limb (yet unnumbered), and another NOAA 14220 emerged at S17E18.
The largest event reported in the past 24 hours was a C3.8 flare at
13:09 UT today (9/16) from NOAA 14220, while the Southeast region
has produced 5 C1 class flares and a C3.2 flare(12:12 UT today).
Yesterday's target, NOAA 14217 also produced 3 low-C class flares
since the last message.
Although these new regions are currently showing more activity than
the target region, it is still uncertain if they grow further or settle.
In the next 24 hours, our target remains to be NOAA 14217, on its
leading sunspot expecting additional C class flares.
The position of the target in NOAA 14217 on 16-September-2025 at
16:00 UT is: S15E49 (-696", -322").
