NOAA's Space Weather Prediction Center says that a strong geomagnetic storm is underway, meaning the northern lights, or aurora borealis, could be visible for much of the northern U.S. Sunday night into Monday morning.

A solar flare observed by the Space Weather Prediction Center on Friday could lead to a colorful display in the sky later tonight for parts of the Pacific Northwest, Upper Midwest, Great Lakes and the Northeast. 

As of Sunday afternoon, the highest observed "planetary K index" was an 8 out of 9. The forecast for Sunday night calls for a Kp index of 6, which could make the northern lights visible in cloud-free spots in the northern United States.

To ensure the best chance at getting a look at the northern lights tonight, look toward the northern horizon. The best viewing conditions are under cloud-free skies and away from bigger cities with light pollution.
