Sunspot Cycle

The Sunspot Cycle is an approximately 11-year pattern of changing solar activity marked by the frequency of sunspots—dark spots on the Sun's surface caused by magnetic activity. During a cycle's peak, sunspots are numerous, and solar activity like solar flares and eruptions increases, which can affect satellites, communications, and power systems on Earth. Conversely, when sunspots are few during a minimum, solar activity diminishes. This cycle is driven by the Sun's magnetic field dynamics, creating a natural rhythm of heightened and reduced activity that influences space weather and Earth's climate in subtle ways.
