It could be a colorful night sky for more than half of millions of people in the northern U.S. as the aurora borealis, or northern lights, could make an appearance in more than half of the country. 

The possibility of seeing the dazzling display comes after the sun had a solar flare erupt on Friday that was directed toward Earth, according to the NOAA’s Space Weather Prediction Center. As a result, 30 states will have the chance to see the the aurora borealis, stretching from Washington to Maine, and as far south as Kansas, the Space Weather Watch says, as long as weather conditions permit. 

“All in all, you can anticipate good conditions for auroral displays,” EarthSky said.

Geomagnetic storm watch

The Space Weather Prediction Center issued a G2 (moderate) geomagnetic storm watch into Sunday night, with a chance of a G3 (strong) developing later in the night. 

The center has a five-level geomagnetic storm scale, with G1 storms registering as minor and G5s considered extreme. A G2 storm typically happens 360 days every 11 years, the center says. 

Where will the northern lights appear?

The northern lights will be possible to see in 30 states, depending on weather conditions like cloud coverage.

“Aurora viewing is likely in the United States tonight as Earth is impacted by a strong solar storm. The most favorable cloud conditions look to be over the Midwest, Plains and parts of the Great Lakes and less favorable conditions in the Northeast and Northwest,” the Space Watch said.
