   GEOMAGNETIC STORM WATCH: Minor G1-class geomagnetic storms are likely for the   
   next three to four days as Earth passes through a stream of high-speed solar   
   wind. A type of shock wave at the leading edge of the stream called a   
   "co-rotating interaction region" (CIR) could spark a display of bright Arctic   
   auroras as early as Dec. 7-8. Visit Spaceweather.com for updates about the   
   coming storms.

   Above: The solar wind stream is spewing from a "coronal hole" in the sun's   
   atmosphere, shown here in an image from NASA's Solar Dynamics Observatory.   
   Coronal holes are regions where the sun's magnetic field opens up and allows   
   solar wind to escape.
