Scientists and meteorites hunters have been on a quest to find bits of rock from the asteroid exploded over the city of Chelyabinsk in Russia on February 15. More than 100 fragments have been found so far that appear to be from the space rock, and now scientists from Russia's Urals Federal University have discovered the biggest chunk so far, a meteorite fragment weighing more than one kilogram (2.2 lbs).

The asteroid has been estimated to be about 15 meters (50 feet) in diameter when it struck Earth's atmosphere, traveling several times the speed of sound, and exploded into a , sending an shockwave to the city below, which broke windows and caused other damage to buildings, injuring about 1,500 people.

Fragments of the have been found along a 50 kilometer (30 mile) trail under the meteorite's . Small meteorites have also been found in an eight-meter (25 feet) wide crater in the region's Lake Chebarkul, scientists said earlier this week. Viktor Grokhovsky from the Urals University believes there are more to be found, including a possible biggest chunk that he says may lie at the bottom of Lake Chebarkul. It could be up to 60cm in diameter, he estimated.

Okay, I'll rerun my post from the other article on the home page.
The biggest single piece if many recovered from the Jilin meteorite strike of March 8th, 1976 weighs in at 1775 kg. If this Russian meteorite is larger, then it should be represented by a larger chunk than that. It remains to be seen. Curious how these events seem to occur more in that region of that hemisphere of the Earth.
