Dear Collaborators,

The target region NOAA 12817 produced numerous B-class activities
as well as two C-class flares (C2.7 and C1.7 in the past two hours,
maybe the former one is from NOAA 12816, to be confirmed). 12817
remains its beta/D-type configuration but increases its sunspot area
and current helicity. Please also note that NOAA 12816 (beta/C-type)
shows some opposite flux emergence in its leading portion though it
is in the decay phase. Further B-class activities are expected and
additional C-class activities are probable, with a very slight chance
of an isolated low M-class flare in the next few days.

The position of NOAA 12817 on April 22 at 03:30 UT is:

N18W81 (896", 306")
