AURORA WATCH: SOHO coronagraphs recorded a full-halo solar coronal mass ejection (CME) on Wednesday that could hit Earth's magnetosphere by week's end. Our planet is already inside a faster-than-usual solar wind stream that could set the stage for auroras when the CME arrives. Visit SpaceWeather.com for details and animations of the CME.
