Summary The frequency distribution ofCp over its range 0 to 2.5 has been determined and is discussed for groups of days selected according to (a) calendar month and (b) season (D, E, J)—1932–1965 inclusive—and for each of eleven year-groups selected in various ways on the basis of the annual mean sunspot number. For each group the median, mean and root-mean-square value ofCp has been found. The results favor the equinoctial hypothesis for the semi-annual variation of geomagnetic disturbance.
