Solar Wind Sparks Auroras
A stream of high-speed solar wind is buffeting Earth's magnetic field, and this is sparking bright auroras around the Arctic Circle. "A geomagnetic storm hit Alaska last night with huge activity seen from horizon to horizon," reports Sacha M. Layos, who sends this picture from Fairbanks:
More auroras are in the offing. NOAA estimates a 50% chance of continued geomagnetic storming on Feb. 3rd as the solar wind continues to blow.
