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. Yohkoh experts can comment on whether this was commonly seen by SXT. This type of evolution was seen in Skylab, though not this clearly (1982; ApJ 266, 359-365).
