Round rainbow over St. Petersburg: a rare sight of a full rainbow

It is impossible to see the full circle of the rainbow from the Earth, its lower part is always closed from our sight. But from an airplane or from a tower crane, as is the case with this video, an extremely fascinating sight opens up.

The video was shot by a crane operator working in St. Petersburg on the construction of the Lakhta Center, a tower 462 meters high, which causes a lot of controversy in the city.
