Dear Collaborators,

The level of solar activity is low. Target region NOAA 12886 has remained
mostly stable, and continues to be classified as an alpha/H-type sunspot
group. This region has again remained flare quiet since the last message.
A coronal loop system (with some prominence/filament structures present)
is visible beyond the South East limb and has been the source of multiple
B-class flares, including the largest event of the period - a B8.7 flare
on 21-Oct-2021 at 15:02 UT (which may have been foot-point occulted, so
actually larger in magnitude). Further B-class activity is expected over
the next 24 hours, with a strong chance for C-class flares.

The approximate position of this region on 21-Oct-2021 at 18:00 UT is:

S23E90 , ( -887", -375" )
