INCOMING CME: A magnetic eruption on the sun during the early hours of
March 15th hurled a coronal mass ejection (CME) directly toward Earth.
NOAA forecasters estimate a 70% chance of polar geomagnetic storms when
the CME arrives on March 17th. High-latitude and possibly even
middle-latitude sky watchers should be alert for auroras this weekend.
