What is THAT ?! Those are not clouds. This isnt aurora either. We just witnessed an amazing airglow here in Atacama desert. Few nights after Geminids meteor shower we had another show on the night sky. It was so intense that one couldnt really see many stars close to the horizon - the sky was literally shining. I write shining because unfortunately one cant see the colors of airglow (its still much less intense then aurora), but a sensitive digital camera is able to capture the phenomenon in its glory. I hope youll enjoy the view !

Were you able to see the wavy banding of the green airglow with the naked eye? Since the green airglow emits at very nearly the same visual wavelength that the human eye is most receptive to, it is easily seen from any truly dark sky location (regardless of whether it is amorphous or banded), but I have never seen red airglow naked eye. Back in October of 2007, I was enjoying an incredibly clear and DARK sky at the annual Okie-Tex Star Party, and decided to make images of the Gegenschein. When the first image came up on the camera, it was streaked with wavy bands of red airglow!! Completely invisible to the naked eye. Not surprising - amateur astronomers use red flashlights at night for the minimal effect they have on dark adaptation.

Yes, I did see the structure visually too, however in B&W only.
