Oooo-weee, CME

SEVERE GEOMAGNETIC STORM PREDICTED: A geomagnetic storm (G1-G3) that sparked auroras as far south as Arizona and Texas on Oct. 7th and 8th is finally over. If you missed the show, good news: more auroras are in the offing. The sun just launched another CME directly toward Earth, and it could cause a severe G4-class storm when it arrives on Oct. 10th.
