Hi Fred,
Yup, I did the Sunspot counts daily for the AAVSO for 8 years a
long time ago. It was nice to see a few groups during the eclipse! The
"K" factor is an individual observer's factor that takes account of
experience of the observer. See:

FWIW: Counting sunspots is a fairly arcane diversion. The generally
accepted [although by no means universally] is the Wolf Number,
Wn=k(10g+s), where g denotes the number of groups [sunspots tend to
come in groups, not always individually discernible], s denotes the
number of individual spots, again somewhat hard to discern, and k is
an "observatory factor", which appears to be much like Einstein's
Cosmological Constant, and can take on any value that makes the data
work as you wish it to. If you see spots, and they are at high solar
latitudes, this augurs well, they may be Cycle 25. If they're on the
solar equator, probably just part of Cycle 24.
All that said, right now there aren't very many G's or S's, and k
could be zero for all we know. I am currently at the point where
living to the Cycle 25 maximum is an immediate goal. [:-)

Sadly, I can only see 3 sunspots today. Down from 6 at the beginning
of the week.
