Dear Collaborators,
Solar activity has continued at a low level in the past 24 hours. The target region produced the largest event, a C3.3 at 23:54 UT yesterday. This region was numbered as NOAA 14191, as it rotated completely onto the disk. 14191 exhibited a sunspot with a well-developed penumbra followed by a small pore, and was classified as an alpha/H-type magnetic configuration. Today, the default target should remain with NOAA 14191. More low-C flares are expected in the following 24 hours.
The position of NOAA 14191 on 21-Aug-2025 at 11:30 UT is:
N10E72 (-889", 128")
