Abstract : Forty years (1 January 1932 to 31 December 1971) of geomagnetic data in terms of the indices Kp and ap were examined. The frequency distributions of these indices and their semiannual and diurnal variations are tabulated and discussed. Frequency tables were generated based on the present value of the index and the succeeding value of the index. These tables clearly demonstrate the persistent nature of Kp and ap. The use of these data as an aid in geomagnetic forecasting is also discussed. (Author)
