Luminescent Night Sky on the Pawnee
First off I want to thank everyone for your enthusiastic support of my photography, my flickr account just passed 5 million views! Five million thanks, think of each of those stars in the sky as a thank you!
What is going on in the sky?
The green glowing sky above here is caused by a phenomena analogous to the northern lights known as airglow. Airglow is caused by the light of electronically and/or vibrationally excited atoms and molecules. Green light from excited oxygen atoms dominates the glow. Below the airglow is a bright layer of light pollution coming from natural gas being flared off on a new oil and gas field to my north near Grover.
I tried to keep the colors as true to life as possible here to not lose the delicate airglow. I took two frames to extend the two-track foreground.
