Mike Taylor in Unity, Maine assembled this composite photo earlier this year. He wrote:
A composite of 175 frames from a time lapse I set up on these train tracks during the awesome auroral display from back in July when the familiar green, magenta and purple colors changed to BLUE as they spiked. This is a blend of all those frames for the sky and a long exposure of just over 4 minutes at a lower ISO to capture the foreground with as little noise as possible. This image has been processed & blended through Lightroom 4 & Photoshop CS5.
