Dear Collaborators,

Solar activity is at a very low level. Target region NOAA 12853 has
decayed further and has shown no signs of flaring activity since the
last message. NOAA 12857 has the most substantial spots on the disk
and is classified as a beta/B-type sunspot group at the start of the
UT day, although it has consolidated some of its intermediate pores
into a spot. NOAA 12857 has been the source of A-class activity and
two B-class flares that were the largest magnitude events since the
last message (a B3.4 flare and a B1.3 flare on 16-Aug-2021 at 07:05
UT and 09:15 UT, respectively). This region becomes the new target,
with B-class activity expected in the next 24 hours.

The position of NOAA 12857 on 16-Aug-2021 at 20:00 UT is:

N18W25 , ( 381", 196" )
