Skies over North America erupted this week with shimmering colors: Shades of pink, purple and green swayed across the skies in Northern as well as some Southern states. It followed two similarly prolific auroral displays in North America in October and May of 2024.

After displays of auroras lit up the sky on Tuesday, another Northern Light array is expected to bring a gleaming light show to the northern part of the U.S. Wednesday.

The northern lights were visible Tuesday night across the Chicago area, illuminating the sky with brightly colorful displays due to severe solar storms.

Auroras may be visible from Alaska to Illinois as an incoming coronal mass ejection could spark severe geomagnetic storm conditions overnight.
