According to the G2 moderate geomagnetic storm watch issued by the Space Weather Prediction Center (SWPC) on Tuesday, the aurora borealis will pop up across the country due to bursts of energy from the sun known as coronal mass ejections (CMEs) that will hit Earth from May 15 to 17.
As the CMEs arrive, there will be two separate windows of time to spot the Northern Lights. One occurred this morning from 5 a.m. to 11 a.m. UTC. Unfortunately, it would have been too light out to really see anything in the sky.
However, the next window, which occurs from 11 a.m. on Thursday to 2 a.m. early Friday morning, could be more promising for stargazers. The SWPC predicts that, along with Alaska, the following states are the most likely to see the celestial phenomenon: Montana, North Dakota, Minnesota, Wisconsin, Michigan, and Maine.
And that’s not all—other states where the Northern Lights could be visible (but are less likely) include Washington, Idaho, Wyoming, South Dakota, Iowa, Illinois, Indiana, Ohio, Pennsylvania, New York, Massachusetts, Vermont, and New Hampshire.
For the best chance at catching a glimpse of the starry skies, experts advise getting as far away from cities and other well-lit areas as possible. “You need very clear skies, a good view of the northern horizon (no trees, buildings, or hills), and it needs to be dark,” an SWPC representative told Thrillist.
