The first observatory to capture images of 2008 TC3 (as its now designated) were Richard Kowalski and colleagues of Mount Lemmon Observatory in Arizona, about 12 hours ago.

The meteor it produces is likely to be spectacular. The rock will release about 1 kiloton of energy in the atmosphere the equivalent of a low-energy nuclear bomb

Harvard astronomer Tim Spahr said the asteroid is so small it can't reach the ground and will not hurt anyone. Astronomers have tracked the sky for years looking for potential comets and asteroids that regularly pelt Earth, but this is the first one they saw coming.

A tiny asteroid discovered just hours ago at an Arizona observatory will enter Earth's atmosphere harmlessly at approximately 10:46 p.m. Eastern time tonight (2:46 a.m. Greenwich Mean Time). There is no danger to people or property since the asteroid will not reach the ground. It is between 3 and 15 feet (1-5 m) in diameter and will burn up in the upper atmosphere, well above aircraft heights. A brilliant fireball will be visible as a result.

The fireball, which could be brilliant, will travel west to east (from azimuth = 281 degrees) at a relative atmospheric impact velocity of 12.8 km/s and arrive at a very low angle (19 degrees) to the local horizon. It is very unlikely that any sizable fragments will survive passage through the Earth's atmosphere.

The asteroid is now within ten lunar distances from the Earth-Moon system. H = 30.4, ~ 3 metres
