[edit] Summary

source: http://ydac.mssl.ucl.ac.uk/ydac/

This image is a full-disk view of the X-ray Sun and was produced by the Yohkoh solar observatory in 1991. The structures that can be seen consist of large and hot (>2MK) coronal magnetic structures. This particular image, one of millions, shows a quite active corona from near the maximum of the solar cycle. At the upper right (solar northwest) one can see an "X-ray jet") squirting outwards - this was one of Yohkoh's original discoveries.
