Dear Collaborators,

Solar activity is at a low level. NOAA 12891 has continued to decay
since the last message, and was reclassified as a beta-delta/C-type
sunspot group. Although the delta is small, NOAA 12891 produced the
largest flare of the period (a C1.6 on 5-Nov-2021 at 15:21 UT). The
target region has rotated onto the visible disk to display a mature
leading polarity spot and no trailing polarity spots so far, but it
has not yet been designated a NOAA number. This region appears to
have a beta/H-type sunspot classification and has been the source
of many B-class flares since the last message (the largest being a
B9.5 on 5-Nov-2021 at 15:50 UT). This currently unnumbered region
remains as the target region because of NOAA 12891's decay. Further
B-class activity is expected over the next 24 hours, with a chance
for a C-class flare.

The approximate position of this region on 5-Nov-2021 at 20:00 UT is:

S27E69 , ( -806", -460" )
