Log Hill photographer Tony Litschewski captured this image of the aurora borealis in the early morning hours on May 11, above Ouray, which was taken at 3:12 a.m. using a 15 second exposure. The northern lights were visible this far south due to a geomagnetic storm, which caused the phenomenon with wavy curtains of light. Solar flares and coronal mass ejections create energized particles, which interact with gases in the Earth’s atmosphere to light up the sky. Photo courtesy Tony Litschewski/naturesfinestimages.com
