GEOMAGNETIC STORM: A G1-class polar geomagnetic storm is in progress on March 1st as Earth enters a fast-moving stream of solar wind. This is sparking bright auroras around the Arctic Circle. The solar wind is flowing from a large canyon-shaped hole in the sun's atmosphere and is expected to influence Earth for the next two days. Visit Spaceweather.com for more information and updates.
