People in at least 30 states, including Illinois, were able to catch a glimpse of the northern lights Sunday night, and Monday brings another chance to see them.
According to NOAA’s Space Weather Prediction Center, a “full halo” CME — a large ejection of plasma and magnetic field from the Sun’s corona — occurred Friday, which could cause a “small” to “moderate” geomagnetic storm Sunday. and Monday.
As a result, dancing waves of light, also known as the aurora borealis, appeared across the United States on Sunday night. Those opportunities could extend into Monday night, according to NOAA officials.
