A multicolored blade of light seems poised to strike over a snowy forest in Ivalo, Finland, on January 22. Late last week a NASA satellite witnessed a solar flare and CME from a different active region on the sun. That solar event triggered a round of auroras over the weekend, including the display captured above.
"At approximately 19:00 hrs the night sky over our Guest house was illuminated by the most spectacular display of Northern Lights, which lasted for several hours," photographer Andy Keen wrote on Spaceweather.com.
"The temperatures plummeted to a chilly -25 degrees Centigrade [-13 degrees Fahrenheit]—cold enough to make our lenses freeze and turn our camera bodies white."
