Aurora Alert!

FAST CORONAL MASS EJECTION: A coronal mass ejection (CME) exploded from the vicinity of sunspot 1164 during the late hours of March 7th. It leapt away from the sun traveling ~2200 km/s, making it the fastest CME since Sept. 2005. A movie of the cloud prepared by Karl Battams of the Naval Research Lab shows a possibly substantial Earth-directed component. This CME and at least one other could brush against Earth’s magnetic field on March 9th or 10th. High-latitude sky watchers should be alert for auroras.

Update: The aurora forecast, from The Geophysical Institute at the University of Alaska, is 4 on a scale of ten, ACTIVE. They foresee the aurora just skimming the northern boundary of the US.

Keep an eye on your sky tonight.
