sunspot area

Sunspot area refers to the size of dark spots on the Sun's surface called sunspots. These spots are regions where intense magnetic activity temporarily cools the solar surface, making them appear darker than surrounding areas. The size or area of sunspots varies over time, often increasing during periods of heightened solar activity and decreasing during quieter times. Measuring sunspot area helps scientists understand the Sun’s magnetic cycle and predict solar phenomena like solar flares, which can affect satellite communications, power grids, and other technology on Earth.
