Caption: Two full disk images taken by the X-Ray Telescope
aboard Hinode are taken one solar rotation apart. In the center of the
left hand image are NOAA active regions 10931 and 10932. A rotation
later the active regions have disappeared, but their effect is still
noticeable in the long quiet sun loops.
