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.

WHAT DOES A SOLAR FLARE SOUND LIKE? Saturday's M8-class flare hit Earth with a burst of strong shortwave radio emissions. Today's edition of Spaceweather.com features an audio recording of the blast captured by an amateur astronomer in New Mexico.
