The mysterious craft remains almost completely still for two and a half minutes as a plane flies overhead
This intriguing footage shows a triangular UFO is hovering in the skies over Russian president Vladimir Putin's home city of St Petersburg.
Three static glowing lights formed in a triangle formation are seen burning out from the overcast sky.
As if to prove some skeptics wrong, a plane is seen flying overhead to demonstrate that whatever it is, it is not your normal aircraft.
The object stays completely still throughout the two and a half minute video.
Explanations from viewers on YouTube , where the clip has been viewed more than 68,000 times, range from a parachutist to Chinese lanterns.
Last year, two UFOs were filmed crashing midair above St Petersburg - hometown of Russian premier Vladimir Putin.
