Unbelievable Timelapse Captures a Rare Phenomenon at the Grand Canyon

As a part of Skyglow Project, two filmmakers are producing a set of stunning timelapse videos to point out to the problem of light pollution. In collaboration with the International Dark Sky Association, Skyglow’s two-person team has recorded some of the most stunning views of the night sky in recent memory.

Gavin Heffernan and Harun Mehmedinović managed to capture a phenomenon known as full cloud inversion in the famous Grand Canyon. When cold air is trapped beneath a layer of warm air, it produces a so called a temperature inversion. Combined with sufficient moisture this then turns into a full cloud inversion. According to the National Weather Service it only happens once every few years, when conditions are right. “We were extremely lucky to be there to capture it, and it’s a collection of unique footage not found anywhere else,” Mehmedinovic said.

The film combines images taken on several trips over a two-year period. Anyone wishing to experience the effect for themselves is advised to go between mid-November and January, when their chances will be highest.

This timelapse is a part of the Skyglow project. It draws attention to dangers of light pollution, while showing the contrast with some of the most incredible dark sky areas in North America. “The Grand Canyon is one of the best dark sky spots in the country and recently got provisional dark-sky park status from international dark-sky association,” says Mehmedinović. “So, this will be a year of dark skies events for them, and it looks like we will have a Skyglow event there as well this summer.”
