The northern lights — also called aurora borealis — could be visible in Alaska, Washington, Montana, North Dakota, Minnesota, Michigan, Maine, northern parts of Idaho, Wyoming, Iowa, New York, Vermont and New Hampshire.

Some minor geomagnetic storms are possible because of a cooler, less dense spot on the sun’s surface, forecasters said.

Space weather forecasters say northern lights may be visible in parts of the northern United States following weekend solar storms.
