Spectacular Moment Rare ‘Rainbow Cloud’ Appears In Skies Above Brazil

This is the moment a spectacular “rainbow cloud” appeared in the skies above Ribeirao Claro in Brazil.

The stunning meteorological phenomenon is known as a cloud iridescence and is caused by clouds that are very thin and are made of similar-sized droplets of water.

André Luiz Nassif captured the beautiful sight at Fazenda São João, a tourist spot near Parana, and says it was visible for about half an hour.
