No, it shattered. Hitting the lower atmosphere at those speeds is like hitting concrete. They are estimating a mass of about 10 tonnes, about a cubic meter in size.Big things come in small packages
Quote from: mlindner on 02/15/2013 02:16 pmThe meteorite didn't detonate. The explosion sounds are pieces of the meteorite going supersonic/hypersonic velocities with the largest piece having the loudest initial bang.Edit: Large impact crater!Another shockwave video:Your first video is of something completely different... Entirely terrestrial.

Large impact crater!

Hi there, As you probably have heard, today, February 15th, a 150-foot (45 meter) asteroid is whizzing by the Earth a hair’s breath from the surface. Missing us by only 14,000 miles, well within the 22,300 mile orbit of the Geostationary satellites that orbit around the Earth’s equator. I wanted to put this in perspective for you with some of the chilling and fascinating facts:This is approximately the same size as the asteroid that hit the Earth in Russia in Siberia (the “Tunguska Event”) on June 30th 1908. That impact was equivalent to 1,000 Hiroshima nuclear bombs & knocked down 80 million trees down over an area covering 2,150 square kilometers (830 sq mi). Had it hit near a population center it would have killed millions of people. Today, there are approximately 610,000 asteroids that are actively tracked in our Solar System. This number represents less than one percent of the more than 60 million asteroids that orbit the Sun.

Here's the location:
The meteorite didn't detonate.

Bad astronomy blog is pretty certain because of the large time displacement between the two which would put the two rocks on very different orbits.

Prof Alan Fitzsimmons, of the Astrophysics Research Centre at Queen's University Belfast, said there was "almost definitely" no connection."One reason is that 2012 DA14 is approaching Earth from the south, and this object hit in the northern hemisphere," he told BBC News.
He is not responding to Jorge's argument.
