Yet another geomagnetic storm could bring the northern lights to parts of the U.S. overnight. On Monday, NOAA’s Space Weather Prediction Center (SWPC) issued a G2-level geomagnetic storm watch, saying a coronal mass ejection (CME) is expected to impact Earth on Wednesday.

The Northern Lights happen when the CMEs hit Earth’s atmosphere. After colliding with the atmosphere, the charged particles scatter toward the poles and get trapped in our planet’s magnetic field.

Stargazers may be able to see the northern lights in Wisconsin, North Dakota, South Dakota, Michigan, Montana, Minnesota, Maine and the northernmost part of New York. The best time to see the northern lights will be around 4 a.m. on Wednesday.

A solar storm could bring the northern lights to the northern United States this week, the National Oceanic Atmospheric Administration said.

As daunting as those terms may sound, this geomagnetic activity will most likely go unnoticed by many — except, of course, those lucky enough to see the northern lights as a res
