Dear Collaborators,
Solar activity has dropped to a very low level since the last message. The largest event was a B7.3 flare at 22:19 UT yesterday from the target region NOAA 14392. This region still shows a beta-gamma/C-type magnetic configuration and remains the largest sunspot area on the disk. Today, the target shall continue at this region. Elsewhere, two regions including NOAA 14397 (N17E50, beta/C-type) in the northeast quadrant produced three low-to-mid B-class flares. B-class activity is expected, with a low-C flare likely in the next 24 hours.
The position of NOAA 14392 on 20-Mar-2026 08:30 UT is:
S17W31 (476", -183")
