The question on the long-term solar cycles is still open. I choose the stable solar cycles in terms of the sampling and differencing stability in samplogram, the time stability or stationarity in wavelet scalogram and the modulation analysis. The short-term solar cycles are also little known due to the strong randomness of solar activity. I found the stable cycles near to the orbital cycles of all major planets upto the Saturn. This may imply a possible planetary forcing of solar activity.
