From ABC News: The northern lights could light up the skies across several parts of the United States on Monday due to a geomagnetic storm, according to space and weather experts.
The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center has issued a geometric storm watch that could produce auroras — described as the “light show after the storm in space” — in 18 U.S. states.
The geometric storm is caused by the “anticipated arrival of the symmetric full-halo Coronal Mass Ejection,” which is the “eruption of solar material and magnetic fields,” according to NOAA.
In a press release, NOAA said the phenomenon “can often be observed somewhere on Earth from just after sunset or just before sunrise. The aurora is not visible during daylight hours.”
It is expected to be visible from the states of: Montana, North Dakota, Minnesota, Washington, South Dakota, Michigan, Maine, Vermont, New Hampshire, Idaho, Alaska, Oregon, New York, Illinois, Nebraska, Iowa, Wyoming and Wisconsin.
A full-halo CME was observed 30 Aug. It is expected to arrive at Earth late afternoon of 1 Sep EDT and continue into early morning of 2 Sep. Confidence of Earth arrival is high, timing and intensity certainty is fair – with a chance for G4. Visit https://t.co/TV7Yw6Lq1Y for more pic.twitter.com/jzExdFFjwG

The Space Weather Prediction Center is predicting a G3 (Strong) Geomagnetic Storm tonight which may allow for northern lights to be visible as far south as Indiana. Mostly clear skies will help to create favorable conditions for viewing but bundle up with temps in the 50s. #INwx pic.twitter.com/EMqeOlbNFN
