Dear Collaborators,

Solar activity is at a low-to-moderate level. Target region NOAA 13645 has now rotated over the South West limb. The most flare-productive region in the period was NOAA 13638 that has now rotated up to the South West limb (where it was classified as a beta/C-type sunspot group the previous day). NOAA 13638 was the source of several C-class flares and an M1.3 flare on 25-Apr-2024 at 17:03 UT (the largest magnitude event). The default target switches to the limb-exiting location of NOAA 13638 because the coronal loop structure will remain visible for most of the next 24 hours. C-class activity is expected over the following 24-hour period, with a chance for a low M-class flare.

The approximate position of this region on 26-Apr-2024 at 14:00 UT is:

S17W90 , ( 911", -278" )
