A mysterious light floating in Moscow at night.

It is an image like a huge light bird.

There are also images that are not so clear, either because they shoot hurriedly.

Some of the lights are shaped like circles.

I feel like a glowing cloud when I look up.

A picture was taken around 2 o'clock in the midnight. It is said that the light was traveling at the same speed as the airplane. What exactly is the identity of this light?
