Analysis of the 5303 ~ coronal line intensity and of the sunspot activity during the period 1962-1970 confirms the existence of two distinct maxima of solar activity, in accordance with the previous findings of Gnevyshev for the period 1954-1960.

The record of flare incidence from January 1969 to October 1988 indicates that the north-south (N-S) distribution of large flares is periodic and approximately in phase with the 11-year sunspot cycle. These data are based on observations of the whole-disk Sun in continuum soft X-rays which commenced
