SOLAR WIND STORM: The Arctic Circle is glowing with auroras as Earth enters a stream of fast-moving solar wind. Minor G1-class geomagnetic storms are likely on Feb. 1st with a chance of stronger G2-class storming as well. If the G2-class storms materialize, auroras could become visible from northern-tier US States along a line from Maine to Washington. Visit Spaceweather.com for more information and updates.
