Image of the Sun, taken by the SECCHI Extreme Ultraviolet Imager (EUVI)
on the STEREO Behind observatory on February 9, 2008 at 05:55:46 UT.
The 195 Angstrom bandpass is sensitive to the Fe XII ionization state
of iron, at a characteristic temperature of about 1.4 million degrees Kelvin.
This image was produced from the STEREO space weather beacon telemetry.
Because of the high amount of compression used for the space weather beacon,
the image quality is far lower than in the final science product.
