Frame:   Speed: (frames/sec)
Range Start: Range Stop:


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.
