"A small asteroid was headed for a fiery but harmless dive into Earth's atmosphere early Tuesday morning over Africa, astronomers said in a first of its kind advance warning.

Harvard scientists announced late Monday afternoon that the asteroid 2008 TC3 would burn up in the sky, making a fireball potentially visible to people in northern Africa. Measuring between 3 feet and 15 feet in diameter, the rock was expected to enter Earth's atmosphere above Sudan at 10:46 p.m. EDT Monday, just before dawn in Africa.

Harvard astronomer Tim Spahr said the asteroid was so small it wouldn't reach the ground before burning up and wouldn't hurt anyone, but the fireball should be seen heading from west to east."
