The peculiar sighting is just one of several to have been reported over the Russian capital recently.
Filmed on Monday, the video was recorded in Moscow’s Marfino District where witness Vladimir Tillman spotted an unknown glowing object high up above a nearby building.
The footage, which was filmed from the ground, shows the object moving in and out of view.
While no conclusive explanation for the sighting has yet been put forward, some Internet users have suggested that it could be a helicopter with a spotlight conducting a search of the area.
Others, meanwhile, maintain that it is definitely not a conventional aircraft.
“You can see this UFO quite often in Moscow, I’ve seen it two times this year,” said local resident Vasya Mirny. “They are even more frequent in other cities.”
Since appearing online last week, the video has already racked up tens of thousands of views.
