A solar wind gust hit Earth's magnetic field on Nov. 27th, sparking a geomagnetic storm (Kp=6) and an outburst of auroras that surprised onlookers. "We experienced an explosion of Northern Lights," reports Therese van Nieuwenhoven of the Polar Light Center in Lofoten, Norway.

"Suddenly, our magnetometers began to show big activity and we could see the most beautiful and moving auroras."

"I did not expect auroras tonight," adds Bjørn Jørgensen of Tromso, Norway, "but suddenly there was a huge, powerful outburst that lasted for about an hour and a half."
