*Captions:* * Blue (171 Angstroms) full disk image: The Sun's million degree atmosphere taken on Dec. 4 by STEREO's SECCHI/EUVI telescope. The close-up of the active region is cropped from the full disk image. * Blue (171 Angstroms): The Sun's million degree atmosphere taken on Dec. 4 by STEREO's SECCHI/EUVI telescope. Close-up of the active region cropped from the full disk image. * Orange (304 Angstroms) full disk: The orange image shows portions of the sun's atmosphere at 60,000 to 80,000 C taken on Dec. 4 by STEREO's SECCHI/EUVI telescope.

Taken by SOHO's MDI instrument. * The first coronal mass ejection (CME) observed by STEREO. This image was taken on Dec. 9 with STEREO's SECCHI/Cor2 coronagraph. A coronagraph blocks the bright disk of the sun allowing scientists to see the Sun's faint outer atmosphere, the corona. The white circle shows the location of the solar disk. The mass ejection can be seen on the right hand side of the image as outward directed streak ending in a faint ring.
