INCOMING CMEs: One and perhaps two CMEs are expected to hit Earth's magnetic field today. Of particular interest is a CME launched toward Earth by a powerful M8-class eruption on March 10. Forecasters say the cloud could spark minor to severe geomagnetic storms when it arrives on March 11-12. High-latitude sky watchers should be alert for auroras tonight.
