Moscovites are excited about a ball of light floating over houses in the capital city's skies. It has triggered a wave of excitement among alien hunters, who want to know what lies behind the strange light.

It happened on October 3, when residents spotted the light flying over homes in the Marfino District of Moscow.

A video of the sight was captured by a witness and uploaded on the Net. It hit the public eye through a UFO insiders page on Russian-based social networking site, VK.

The ball of light hovers over homes, and then flies out of sight.

This incident follows a similar bizarre incident last month. REN TV telecast the views of three pilots who said they had seen an eerie glowing object over Tomsk in Siberia. The mysterious light had even made the Russian, Chinese and Korean pilots panic.

Comments in YouTube show that UFOs are common in Russia, and are "quite often" spotted in Moscow, Volgograd and Astrakhan.

Local man Vasya Mirny said: 'You can see this UFO quite often in Moscow, I've seen it two times this year. They are even more frequent in other cities.'

Another, Yulia, added: 'I have no idea what this thing was. UFO is the first thing which comes to mind.'

No explanation has been forthcoming from either officials or other authorities.
