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" )
