Aurora over Wisconsin Tony Wilder/Milwaukee Journal-Sentinel via NASA/SDO

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.

This post mistakenly credited the above image to Jesper Grønne of Denmark, the credit stated on the SDO mission blog. The photo was taken in Wisconsin by Mark Wilder.
