Figure 3. Four panels showing the decomposition of sunspot groups by cycle membership. This is unambiguously determined from their magnetic polarities. The bottom three panels show recent minimum periods; our current minimum (the very bottom) shows that the late arrival of new-cycle spots has allowed the number of old-cycle spots, and hence the total spot coverage, to be remarkably low.

Note that the earlier minima had much more overlap between cycles, and hence more activity during their shorter intervals.) |
