The northern lights made an appearance early Sunday in the western United States, but more sightings could be possible as night falls.

On Sunday morning, people in New Mexico, Wyoming, Washington state and other parts of the west reported seeing the aurora borealis. Some even spotted glowing skies in the Mid-Atlantic before dawn.
