After Solar Flare Sprays Earth With Charged Plasma, a Beautiful Aurora

Aurora over Wisconsin

On Sunday, sunspot number 1092 emitted a C-class solar flare--not a large one, by solar flare standards. But NASA scientists were intrigued by what accompanied it--an unusually fast corona mass ejection that sent a large cloud of charged plasma toward Earth. There will be no adverse effects here on Earth--other than increased aurora activity.

This shot was captured by Jesper Grønne in Denmark, and was posted on NASA's Solar Dynamics Observatory blog.
