Aurora Borealis Active from Solar Flares
A blast of plasma from the sun hit the Earth Feb. 18th, creating a brilliant display of lights across the skies of Northern Canada. The lights were the result of a geomagnetic storm caused by three solar flares that blasted toward Earth from the sun between Feb. 13 and Feb. 15, including what NASA called the largest solar flare in four years. The three apparently merged before their arrival, reported the Space Weather Prediction Center run by the U.S. National Oceanographic and Atmospheric Administration. NOAA reported one limited blackout of radio communication in the past 24 hours as a result of geomagnetic activity.
