| Abstract | Abstract In this paper a spectral analysis of the aa geomagnetic index (aa) and of the sunspot number (SSN) time series during the period 1868-1998 is made. The spectral method used was the multiple taper method. The main periods found were related to the 11 year solar cycle and its harmonics. The aa spectrum shows in addition a period of 4.4 years, which is caused by the dual-peak distribution of the aa time series. The cross-correlation for all the periods indicates that aa lags SSN by 1 year, however the correlation is decreasing and the lag is increasing with time. Using averages of 23 years, cross-correlations calculations show that the correlation coefficient decreases from 0.76 to 0.35 and the lag from 0 (1868-1890) to ñ3 (1960-1982). |
