In the Midwest, northern Minnesota, Wisconsin and Michigan’s Upper Peninsula could all see aurora formation Sunday night, according to NOAA’s forecast. Most of North Dakota, Alaska and a large portion of Montana could also see the lights, while small slivers of extreme northern Idaho and northeastern Washington are also within the view line.

A coronal mass ejection hurtling from the sun toward Earth could unleash the northern lights in up to 18 states in the US.
