Earth in the crosshairs


Here's looking at you, Earthlings!

  "Giant sunspot AR1944 erupted on Jan 7th at approximately 1832 UT, producing a powerful X1-class solar flare. First-look coronagraph images from the STEREO-Ahead spacecraft appear to show a coronal mass ejection (CME) emerging from the blast site. If so, the CME is almost certainly heading for Earth. "
