The aurora borealis may light up the night sky in Wisconsin on Monday and Tuesday, according to the NOAA's Space Weather Prediction Center. The SWPC's forecast indicates that the northern lights will stick to the northern portion of the state Monday, but could be visible as far south as central Wisconsin Tuesday.

A strong geomagnetic storm will produce northern lights in nearly two ... nitrogen glows purple or pink, oxygen green. This creates the aurora’s colorful display.
