MIME. links. here. 3 days after the event, eventually some hard evidence [Registered users can see links. ] [Registered users can see links. ] A rare series of events occurred early Tuesday morning, October 7, as asteroid 2008 TC3 hit Earth releasing a huge amount of light and energy before exploding in the atmosphere over northern Sudan. Even better is that amazingly, the Meteosat-8 Rapid Scanning Service managed to capture the impact. This brief flash was captured by Meteosat-8 in Rapid Scan Service, as the image to the right shows. The asteroid 2008 TC3, entered the Earth's atmosphere at a velocity of 12.8 kilometers per second at around 02:46 UTC above northern Sudan, Africa. As it entered the Earth's atmosphere, it compressed the air in front of it. The compression heated the air, which in turn heated the object to create a spectacular fireball, releasing huge amounts of energy as it disintegrated and exploded in the atmosphere, dozens of kilometers above ground. The asteroid exploded with the energy of around one kiloton, equal to the power of a small nuclear bomb. Infrasound detector arrays in Kenya also detected a sound wave from the direction of the expected impact corresponding to the energy of 1.1-2.1 kilotons of TNT. -- General electronic repairs, other than TVs and PCs [Registered users can see links. ] Diverse Devices, Southampton, England |
