Fast Moving Coronal Mass Ejection

On Saturday, November 26, 2011 a solar flare hurled a coronal mass ejection (CME) at about 930 km/s or 2 million mph into Space. This fast moving CME will reach Earth on Monday November 28th. The impact of the ionized particle cloud could trigger a geomagnetic storm with some aurorae sightings in high latitudes. credit: NASA
