This string of multi-colored lights were captured in the sky above San Diego, California, by Larry Fox – who was in his back garden when he spotted the unusual formation.
‘It looked like a strobe light’, he explained.
‘It was a series of flashing lights. ‘If it was a plane it would have moved’.
The strange lights were also spotted by an NBC reporter and photographer, who were covering a story on Tuesday night.

What do you think the lights are?
