The dark feature immediately below and to the right of the bright plume is the shadow being cast by this brief, dust-raising event. The picture is located near 3.5°N, 306.6°W, and covers an area 3 km (1.9 mi) wide. The shadow indicates that this scene is illuminated by sunlight from the upper left.
