One of the largest sunspot groups in years is rotated over the sun's surface at present. With a least four dark cores larger than Earth, AR1476 sprawls more than 100,000 km from end to end. Sunspots are temporary dark patches on the surface of the sun that are caused by intense magnetic activity. These structures sometimes erupt into solar flares, which send high-energy radiation streaming into space.
