Running Time:

On Thursday, June 21, 2001, a total solar eclipse sped across the Southern Hemisphere. The shadow of the moon first darkened the South Atlantic about 250 miles east of the Uruguay coast. It crossed the Atlantic Ocean, traversed southern Africa and the island of Madagascar, and then vanished into the darkness as night fell over the Indian Ocean. We sent our crew to the country of Zambia to bring images of the total solar eclipse as it happened.
