SIBERIA was buzzed overnight by a mysterious ball of fire streaking across the sky.
Videos show the large and bright space object flashing over at least four Russian regions, with witnesses seeing an array of colours as “night turned to day”.
One observer said: “I heard a rumble, then the dogs barked.
“I do not understand what it was.”
Another said: “There was a glow, white and blue.”
One witness saw green flashes while another onlooker said: “It was a white light, and then an explosion.”
The UFO fireball was seen over a distance of some 500 miles covering the sprawling regions of Krasnoyarsk, Tuva, Khakassia, and Kemerovo.
Experts have ruled out a Russian rocket and there is no evidence so far that a meteorite crashed to earth.
It was probably a meteor that burned out in the atmosphere, say experts.
Professor Viktor Grokhovsky, of the Ural Federal University, said: “This ball of fire was most likely a small cosmic body that entered the earth’s atmosphere.”
Roman Moryachkov, from the Siberian Federal University, said: “This guest from outer space is most likely not a meteorite, since it did not reach the earth…
“It burned brightly and for a long time.”
He believes it was probably a meteor that burned out in a spectacular display.
