Dear Collaborators,

Solar activity has remained stable over the past 24 hours. 
The largest event since the last message was a C3.3 flare 
at 19:48 UT yesterday from NOAA 14180. This region has 
been classified as a beta/C-type magnetic configuration with 
the emergence of new negative magnetic fluxes in its leading 
portion in the period. Today, NOAA 14180 should become the 
new default target. Yesterday’s target NOAA 14172 has almost 
rotated out of Earth-view, producing only three ~C1 flares. More 
C-class activity is expected in the following 24 hours.

The position of NOAA 14180 on 18-Aug-2025 at 11:30 UT is:

S03W18 (293", -156")
