The Sun goes through 11-year cycles during which the number of sunspots and the intensity of solar activity increase and reach a peak, bringing the highest likelihood of intense solar storms.

Another, lesser-known repeating pattern in solar activity is the Centennial Gleissberg Cycle (CGC) — a variation in the intensity of sunspot cycles that rises and falls every 80 to 100 years.
