Solar storms are hard to predict like hurricane in Earth. Sun reverses it's polarity of magnetic field every eleven years. So in 22 years it comes back where it was. As we near the reversal, every 11 years the number of sunspot increases and there is a peak in solar activity. We call it solar maximum. Those periods are 5 years apart from solar minimum in which solar activity are lowest.
