A very bright fireball was seen and recorded by NASA's cameras over Pennsylvania, US at 09:45 UTC (04:45 EST) on February 17, 2015.
NASA's Meteoroid Environment Office (MEO) said the space rock was about 60 cm (2 feet) in diameter, weighing roughly 226 kg (500 pounds). It entered Earth’s atmosphere above western Pennsylvania and was first detected by 3 NASA meteor cameras at an altitude of 96.5 km (60 miles) above Beaver Falls.
The fireball moved almost due east at a speed of 72 420 km/h (45 000 mph).
It flared brighter than the Full Moon before the cameras lost track of it at an altitude of 20.9 km (13 miles) above the town of Kittanning.
There may be fragments (meteorites) scattered on the ground east of that location, MEO said.
