Skywatchers are set to be dazzled by the northern lights over the coming hours, as a geomagnetic storm builds.

I got a call at about 4 a.m. alerting me of the trailer roll over,” said Kimberley Maher, the northern region state on-scene coordinator for the Alaska Dept. of Environmental Conservation.

The northern lights should continue well into the weekend and may even reach down into the middle parts of the US.
