	Figure 1: Sunspot activity circa the solar cycle 4. Thin black curve corresponds to the monthly group sunspot numbers. Suggested smoothed sunspot activities for hemispheres are shown by gray thick curves, and their sum - by the black thick curve.

	Figure 2: Sunspot activity circa the solar cycle 20. a) Black thin curve is smoothed monthly means of a sunspot area for the northern and gray thin curve - for the southern hemisphere. The total sunspot area is shown by a thick black curve. b) The same, but with a time-shift of the southern hemispheric activity.

Figure 3: a) Durations of solar cycles versus time. The gray thin curve corresponds to the lengths of group sunspot cycles. The black thick curve shows lengths of smoothed sunspot area cycles. b) The lengths of smoothed monthly sunspot area cycles. The gray solid curve corresponds to the northern hemisphere and gray dashed curve - to the southern hemisphere. Thick black curve represents the total Sun (see Table 1).

Figure 4: Sunspot activity circa the solar cycle 19. a) The smoothed monthly means of sunspot area for the northern (black thin) and southern hemispheres (gray thin). The total sunspot area is shown by a thick black curve. b) Segment of the sunspot activity minimum at the beginning of the solar cycle 19. Arrows mark time moments in which hemispheric and total activities have the lowest values. c) The same but for the end of the 19th cycle.
