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.

The full Sturgeon Moon is expected to reach peak brightness at 3:55 a.m. ET. Skywatchers in the northernmost parts of the country might have the chance to catch a special double feature in the sky tonight—the northern lights, plus the full Sturgeon Moon.
