A geomagnetic storm could make aurora borealis—or the northern lights—visible across parts of the United States overnight Tuesday. The National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center forecast that the northern lights could be visible in up to 16 states.

Minor geomagnetic storms could produce a colorful aurora display in about 15 states Monday night, according to a National Oceanic and Atmospheric Administration forecast.

Another reason to love the last weeks of summer: You may be able to see the northern lights tonight and tomorrow night in over a dozen northern states.
