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 259, 359-365).
