AURORA WATCH: A moderate geomagnetic storm that began Monday when a solar coronal mass ejection buffeted Earth's magnetic field shows no immediate signs of abating. High-latitude sky watchers should be alert for auroras after local nightfall.

HERE COMES THE SUN: Another coronal mass ejection is heading our way. SOHO coronagraphs spotted a very faint CME on Monday that could arrive in the neighborhood of our planet on March 22nd or 23rd.
