A long, bright loop wraps around the southeast (lower left) limb of the Sun. This bright loop is extremely hot and it's sudden appearance causes a slow moving million degree heat wave to cross the south. Just north of the heat wave is a nice cool coronal hole.
The Hinode XRT takes daily synoptic images to study large scale phenomena in the solar corona. You can find images at
Synoptic Composite Image Archive (SCIA).
