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. [:-)
