Unfortunately, this isn't quite as exciting as it seems. Because of the way
that sunspots are counted, the lowest number where there is even a single
sunspot present is 11, which means one group of sunspots with one spot.
Basically, you take the number of groups and multiply by ten, then add in
the number of spots. So in this case, 12 actually means one group with 2
spots.
Here's a bit more info on how this is computed:
