NASA has reported that last December, military satellites detected a huge fireball over the Barents Sea.
The meteor entered the atmosphere on 18th December 2018 travelling at about 30 km/s. It was probably several metres in diameter and exploded with an energy equivalent of about 170 kilotons , which makes it one of the largest meteors to enter our atmosphere this century and about 40% as large as the Chelyabinsk event. It broke up about 25km over the Barents Sea between the USA and Russia. It wasn’t reported earlier as this is a quite remote area, and the military satellite data was not made available earlier.
A video showing the smoke trail has been constructed from satellite data was posted on twitter :
