Dear Collaborators,
Solar activity has reached a high-B level since the last message. Ten B-class flares were produced by two regions near the east limb. The region in the northern quadrant generated the largest event, a B9.9 flare at 01:09 UT and a B5 flare. The region in the southern quadrant produced eight B-class flares, with its largest being a B8.4 at 08:12 UT. Today, the target will switch to the southeast limb region. B-class activity is expected over the following 24 hours.
The approximate position of the target on 19-Sep-2026 11:30 UT is:
S12E77 (-910", 200")
