Dear Collaborators,

The target region NOAA 12816 produced an M1.1 flare at 04/19/23:19 UT
and also a B8.0 flare, which were the largest two X-ray events of the period.
12816 has been classified as a beta/D-type region, increasing in the sunspot
area and number of spots. It continues to show flux emergencies and also
cancellations. The newly emerged region mentioned in the last message
was designated as NOAA 12817 (N18W50) with a beta/B-type region. This
region has produced numerous B-class flares. Further B-class activities are
expected and some C-class activities are probable in the following 24 hours.

The position of NOAA 12816 on April 20 at 15:30 UT is:

S24E17 (-256", -312")
