The National Weather Service tweeted photos of the light show calling it "probably the best #aurora light display we've seen in a decade here in #Seattle. Simply amazing."
In the Northern Hemisphere, the aurora borealis, also called the "northern lights," occurs when particles from space interact with electrically charged particles in the Earth's magnetic field.
The particles in space, fueled by energy from the sun, collide with particles in the Earth's magnetic field and emit light, which in most cases is viewed as the color green in the sky.
We just witnessed an amazing auroral display here at NWS Seattle. Curtains extending well up into sky. Photos and video will follow later.— NWS Seattle (@NWSSeattle) May 8, 2016
