"Rare Northern Lights Show to Illuminate Skies Across Multiple US States"

The Northern Lights, also known as the aurora borealis, may be visible in the skies of Chicago starting Wednesday night into Thursday morning. The lights could also be seen in Minneapolis, Milwaukee, and several other states. Clear weather is needed to see the phenomenon, and the best viewing time in Chicago is between 10 p.m. and 2 a.m. However, the unpredictability of auroras and changing weather conditions make it difficult to determine the perfect time to observe them. To increase chances of seeing the lights, it is recommended to find a dark location away from light pollution and allow the eyes to adjust to the darkness. The Northern Lights occur when charged particles from the sun interact with Earth's magnetic field, creating a beautiful display of glowing atmospheric gases.
