It lept away from the sun traveling some 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 seems to show a small but non-negligible 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.
