Moon Shadow Moves Over Africa - When the Moon's shadow reached out and touched the Earth June 21, 2001, the result was a solar eclipse. Such an eclipse is total only for observers located along a narrow path corresponding to the ground track of the shadow's dark central portion or umbra. For this eclipse, racing along at nearly 2000 kilometers per hour, the Moon's umbra obligingly crossed over land along regions of Africa and Australia. Totality lasted for about two minutes or less at a given location. Astronomy Picture of the Day: Eclipse
