Spanning the interval 06:55 -- 07:12 UT of 23 April 1998, this
movie shows downflow above the arcade in the form of X-ray voids. The
upper arrow indicates the approximate location of some features which
approach the top of the arcade near the end of the movie. The direction
of motion of these particular features is distinctly non-radial; a
heliographic coordinate grid is shown to emphasize the location of the
solar limb. The speed of the motion in the north is approximately 370 km
s$^{-1}$ in the plane of the sky. Downward flows
can also be detected other parts of the arcade, in particular above the
position indicated by the lower arrow.
