Dear Collaborators,
Solar activity returned to a very low level since the last message. The largest event in the past 24 hours was a C2.6 flare at 16:58 UT yesterday (9/16) from NOAA 14216, while the target region, NOAA 14217 showed no flare activity since the last message.
NOAA 14220 is a bipolar region that emerged yesterday now approaching the Southern central meridian. Although this region produced only low-C class flares in the past 24 hours, it is worth noting that its trailing (positive polarity) sunspot appears to be larger and is located at lower latitude than its leading portion. Today, we will switch the default target to this region, NOAA 14220.
The position of the target in NOAA 14220 on 17-September-2025 at 16:30 UT is: S17E04 (-67", -402").
