With a little bit of luck and the right conditions, folks in Wisconsin could get a peek at the aurora borealis Sunday night.

The best time to see the northern lights in Wisconsin should be between 10 p.m. Sunday and 1 a.m. Monday, according to the National Oceanic and Atmospheric Administration's radar. 

The illuminated sky is the result of a solar flare that erupted out of a sunspot late Thursday into early Friday. The flare released a wave of charged particles that take a few days to reach Earth. The northern lights form when those sun particles meet the Earth's magnetic field. The particles interact with molecules of atmospheric gases to create the famed glowing red and green colors.

The National Oceanic and Atmospheric Administration issued a geomagnetic storm watch Friday and expects a "moderate" storm, a 2 out of 5 on its severity scale.
