Dear Collaborators,

Solar activity is at a low-to-moderate level. Target region NOAA 13380 was stable in terms of sunspot area since the last message and has been confirmed as a beta/C-type sunspot group now that it is fully on disk. This region was the source of low C-class activity in the period while NOAA 13376 produced a C-class flare and the largest magnitude flare, an M1.5 on 25-Jul-2023 at 01:36 UT. NOAA 13376 has undergone a significant episode of flux emergence and consolidation over the past 48 hours to evolve from an alpha/H-type sunspot group into a compact beta/D-type, so it becomes the new default target region. Further C-class flaring is expected in the next 24 hours, with a chance for another M-class flare.

The position of NOAA 13376 on 25-Jul-2023 at 13:00 UT is:

N23W60 , ( 755", 328" )
