On February 15, 2013 a meteorite exploded in the atmosphere at approximately 14.5 miles above the town of Chelyabinsk, Russia. The meteorite entered Earth's atmosphere at about 41,000 mph and was 17 meters (50 ft) in diameter. The impact was so great that it drew attention to EarthScope's USArray Transportable Array stations on the east coast of North America.
