Northern Lights display expected for 2nd night in a row for these US states

(NEW YORK) — Dazzling waves of color are lighting up the skies this week.

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

The auroras are being caused by one of the strongest geomagnetic storms of the year, which occurs when electrons from the sun collide with Earth’s magnetic field to produce colored lights, according to NOAA.

“Aurora is the name given to the glow or light produced when electrons from space flow down Earth’s magnetic field and collide with atoms and molecules of the upper atmosphere in a ring or oval centered on the magnetic pole of Earth. The collisions produce light much like how electrons flowing through gas in a neon light
