Glossary term: Solar Cycle
Description: The solar cycle is the approximately 11-year cycle in the number of sunspots, solar flares, and other forms of activity on the Sun. This activity is generated, in part, by the Sun's general magnetic field. Since that magnetic field switches between north and south polarity in alternate cycles, the solar cycle is sometimes considered to be a 22-year cycle.Related Terms:
