The complete figure set (2 images) is available in the online journal.

Nest-member ARs during Solar Cycle 24 shown in longitude–time coordinates for the north (top) and south (bottom) hemispheres. ARs are sampled nearest central meridian passage and restricted to areas greater than 50 μHem. Symbol size is proportional to AR area, while ARs belonging to the same nest are plotted with the same color. ARs that do not participate in nests are shown as light gray symbols in the background. The hemispheres exhibit distinct bursts of nested activity that occur at different times and longitudes. The corresponding figures for Solar Cycles 22 and 23 are available.
