No brain today. The graph is the DAILY sunspot count, not monthly.
Sorry(tm).

Well, we have the Maunder Minimum which lasted about 70 years, the
Dalton Minimum which lasted 40 years, and a few others that lasted
maybe 5 years. All corresponded to global cooling and miniature ice
ages. That begs the question whether a one day drop in the sunspot
count is worthy of a unique name. Certainly some governing body could
award the naming of a sunspot minimum to the first observer who
notices the lack of sunspots. I would volunteer to be the first to
have a one day sunspot minimum named after me, but since I wasn't the
first to notice, the prize should go to someone else.

More to the point of this group, the 2.8GHz (10.7cm) solar flux
follows the sunspot cycle. For propagation, I guess that's more
interesting than counting suspots.

Looks like 2.8GHz radio flux dropped as fast as the sunspot count.
