What does that mean?
That is a small burst by fireball standards: the Chelyabinsk fireball of 2013 released about 440 kilotons. If the object was stony rock entering at a typical 20 km/s, it was roughly 1 metres across and weighed around 1.6 tonnes.
Most objects of this kind break up and burn away high in the atmosphere, but larger ones can drop small meteorites. About 70% of Earth is ocean, so most fireballs like this fall into the sea.
