Sunspot 9393 covers an area of the sun equivalent to the combined surface area of 13 Earths. A sunspot is a magnetic disturbance of the photosphere. Like clouds in the Earth's atmosphere, they only have a limited lifetime. A spot is composed of a dark, central area called an umbra, and a filamentous peripheral area, the penumbra.
