Zusammenfassung:An extension of anharmonic frequency analysis (AFA) is used to analyze and extrapolate the sunspot numbers. The higher resolution possible with this new approach in principle permits a better accuracy of the prediction for a given extrapolation range, provided the time series is stationary. The results indicate that the extremas of the sunspot numbers of the next three solar cycles will not exceed a magnitude of 100 significantly.
