Dear Collaborators,
Solar activity continues to be low since the last message. Yesterday's target, NOAA 14216 did not show further activity during the past 24 hours, while NOAA 14220 resumed to produce flares with the largest being a C3.4 flare at 19:57 UT yesterday (9/20).
Today, the default target will switch back to NOAA 14220, on the area of mixed polarity of the trailing sunspot. Additional C class activities are expected.
The position of the target in NOAA 14220 on 21-September-2025 at 15:30 UT is: S18W47 (673", -368").
