New Method to Predict Sunspot Numbers and Some Interplanetary Parameters for the Next Solar Maximum

Using smoothed sunspot numbers (SSN) for all previous solar cycles, we predict the amplitude and mean of SSN for cycle 24. We compare our results with other predictions. On the basis of our prediction for SSN, we put forward a forecast of the solar wind quasi-invariant (QI) and helium abundance in the interplanetary space at 1 Au.
