LECCE, Italy, Jan. 22 (UPI) -- A multicolor light phenomenon known as a "fire rainbow," or circumhorizontal arc, was caught on camera in the sky over southern Italy.

The video was filmed Jan. 9 over the city of Lecce.

The phenomenon is caused by light from the sun or moon refracting off plate-shaped ice crystals suspended among the clouds in the atmosphere.

It is nicknamed a "fire rainbow" despite being neither a rainbow nor fire-related because the halo sometimes manifests in a way that resembles flames.
