Dear Collaborators,
Solar activity has been at a low level since the last message. The largest event in the past 24 hours was a C5.3 flare at 05:45 UT today(5/20) from a region appeared from the Southeast limb at latitude of ~6 degrees. This unnumbered region also produced 2 high-B and 5 low-C class flares in the past 24 hours.
Yesterday's target from the Northeast limb turned out to be a plage with small sunspots and does not have an NOAA number yet. This region only produced a B8.9 flare(20:01 UT on 5/19) after the M3.2 event yesterday.
Today, we will switch our default target to the unnumbered region from the Southeast limb, because of the more frequent flare history than the Northeast region (yesterday's target) in the past 24 hours. Additional C class events or larger are expected.
The position of the target on 20-May-2025 at 16:00 UT is: S07E71 (-890", -105").
