CORONAL ECLIPSE IMAGE

This image shows the difference between two SXT images obtained during
the "coronal eclipse" of Nov. 13, 1993. The bright red part of the
difference image shows the smooth radial fall-off of coronal brightness
at the heliographic SW limb of the Sun. The differencing allows for a
cancellation of the stray light and dark current in the SXT images, and
gives the clearest possible view of the faint coronal brightness. The
complicated structure of residual brightness on the solar disk (top of
image) results from a small change in telecope pointing in the eight
minutes between images. At the time of the reference image, the Moon
was at the bottom of the image and is invisible against the coronal
brightness.
