This is an animated gif sequence of a "Mystery" or "Ghost" light in the Tularosa Basin of New Mexico. The light's source is the headlight array from a locomotive. You can see the effects of a complex superior mirage above the ground, and the light itself refracted to the viewer, making it look "otherworldly." Note also the greenish hue of the superior, refracted image, as this is another result of this form of extreme refraction (similar mechanism that produces the Green Flash). This is the same type of atmospheric situation that viewers witness with the most fanciful of the Marfa Mystery Lights (with car headlights). The mirage has elements of the Fata Morgana Mirage. Photographed from White Sands National Monument in March of 2008 with a Nikon D300 fitted with a 200-400 f/4 lens with a 1.7x teleconverter, looking east.
Also, the camera wasn't shaking, but the whole scene was being refracted and thus "moved."

Here it is at a reduced frame rate
