A giant solar storm swept across the northern hemisphere yesterday, bringing with it some amazing views of the Aurora Borealis. People across the globe—the U.K., New York, Seattle—spotted incredible Northern Lights activity.
The Space Weather Prediction Center (SWPC), also issued a geomagnetic storm watch through Friday, which means there's still a chance to catch some major aurora activity tonight.
For those on the lookout, check out @AuraralActivity on Twitter—the account tracks when the auroras are "unsettled," which means they can be spotted from the ground.
