Dear Collaborators,

Solar activity is at a moderate level. Target region NOAA 13229 grew slightly since the last message and was reclassified as a beta-delta/E-type sunspot group. This region has produced four C-class flares in the period, the largest being a C5.5 flare on 20-Feb-2023 at 17:37 UT. A new spot region is in the process of rotating over the North East limb and has already produced four C-class flares and the largest magnitude flare of the period - a foot-point occulted M4.4 on 20-Feb-2023 at 14:47 UT (therefore of actually larger peak magnitude). The MM#003 Major Flare Watch will remain in effect, but the target switches to this currently unnumbered region at the North East limb. More C-class activity is expected over the next 24 hours, with a good chance for M-class flares.

The approximate position of this region on 20-Feb-2023 at 19:00 UT is:

N26E90 , ( -871", 422" )
