Solar cycles average about 11 years each. The eleven year cycle is measured by changes in the Sun's output, ejection of solar materials, sunspots, and auroras on Earth. Sometimes the cycle is referred to as a 22-year one since the sunspot activity reverses solar hemispheres (changes polarity) in alternating cycles.
