The CME that is heading for Earth right now.
Yesterday, the Sun blasted a coronal mass ejection (CME) straight in Earth's direction. According to the experts on Spaceweather.com, the CME is projected to hit Earth sometime tomorrow evening for people living in the Eastern United States. Needless to say, one should be alert for aurora tomorrow night, and this does not apply just to high-latitude skywatchers, either.
