From spaceweather.com: ASTEROID 2008 TC3: A small, newly-discovered asteroid named 2008 TC3 is approaching Earth and chances are good that it will hit. Steve Chesley of JPL estimates that atmospheric entry will occur on Oct 7th at 0246 UTC over northern Sudan [ref]. Measuring only a few meters across, the space rock poses no threat to the ground, but it should create a spectacular fireball, releasing about a kiloton of energy as it disintegrates and explodes in the atmosphere. patrick
