Solar cycles refer to the periodic changes in the Sun's activity and appearance, primarily driven by its magnetic field. These cycles typically last about 11 years and are characterized by variations in the number of sunspots, solar flares, and solar radiation. During the peak of a solar cycle, known as solar maximum, sunspots are more numerous, and solar activity is heightened. The solar cycle influences space weather, which can affect satellite operations, communication systems, and even power grids on Earth. Understanding solar cycles is crucial for predicting these effects and ensuring the safety of technology that relies on Earth's magnetic field and solar energy.
