Prediction of solar minimum and maximum epochs on the basis of spectral characteristics for the next millennium

A prevision of solar activity minimum and maximum epochs for the next 1000 years was obtained using a sum of sine waves derived from spectral analysis of the time series of 10 years average sunspot number for the period 1016–2006. The predicted 1000 year solar activity evidence the possibility of forthcoming four minima and one maximum. The 10 years average sunspot number activity in each anomalous period was used in linear equations to obtain estimates of the solar irradiance, solar wind velocity, and the southward component of the interplanetary magnetic field.
