A strong geomagnetic storm in Earth's atmosphere made for a spectacular show of the Northern Lights in Minnesota overnight.

A strong (G3 class) geomagnetic storm on the sun is sending pulses of energy toward Earth. As the particles interact with Earth’s magnetosphere, they may trigger a display of northern lights Thursday night and possibly again Friday night. You can see the southward extent of the auroral oval across Minnesota in the image at the top of this post.

Minnesotans could get the chance to see the Northern Lights on Thursday as a “strong" geomagnetic storm is underway.
