McKenzie, Enclosure 1
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 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.
The movie will repeat.
