A monster solar flare erupted early Sunday (Oct. 19) from a huge sunspot that may just be getting warmed up.
The sun fired off an X-class solar flare — the most powerful type — that peaked at 1:01 a.m. EDT (5:01 GMT) Sunday. NASA's Solar Dynamics Observatory (SDO) spacecraft captured photos and video of the intense sun storm, which researchers classified as an X1.1 flare.
The flare erupted from a sunspot called AR (Active Region) 2192, which has since grown to become 78,000 miles (125,000 kilometers) wide, according to Spaceweather.com — almost as big as the planet Jupiter.
