The sunspot record for the time interval 1749-1977 can be represented conveniently by an harmonic model comprising a relatively large number of lines. Solar activity can otherwise be considered as a sequence of partly overlapping events, triggered periodically at intervals of the order of 11 years.

The average rate of growth during the ascending portion of the sunspot cycle, defined here as the difference in smoothed sunspot number values between elapsed time (in months) t and sunspot minimum divided by t, is shown to correlate (r > 0.78) with the size of the sunspot cycle, especially for t >

Examined are associational aspects as they relate the maximum amplitude R M for the sunspot cycle to the rate of rise Ral during the ascending phase, where R M is the smoothed sunspot number at cycle maximum and Rat is the sum of the monthly mean sunspot numbers for selected 6-month intervals (At) m
