Dec 18, 2024 · The Sun goes through a pattern of magnetic activity known as the solar cycle. During each cycle, the Sun experiences a very active period called “solar maximum” and a less active period called “solar minimum.” During solar maximum, increased magnetic activity creates sunspots. These appear as darker, cooler spots on the Sun’s surface.
