A bizarre video has emerged of what seems to be two suns setting opposite each other.

In the footage, shot in Harrow, UK late last year, the camera pans from one 'sunset' to the other.

"Whilst going on a walk I was amazed to see two sunsets on opposite sides of the sky," the filmer wrote online.

"One up ahead was the genuine sunset based on the direction, whilst the other was somehow perfectly opposite it on the horizon."
