The distance (km) of the leading edge of the shock - the initial speed was approximately 318 km/sec, while the average speed was 226 km/sec. The speeds were measured in the image plane.

In each EIT image showing the event, regions could be identified as areas of enhanced emission due to the shock. Seven regions were outlined and tracked for changes in intensity. The intensity variations are included on a separate page.
