PICTURE OF THE DAY

In a wonderful convergence of events, we not only had one of the best displays of aurora in the past decade, but also the peak of the firefly season and a setting crescent Moon.

An aurora and fireflies

This photographer’s report speaks for itself: In a wonderful convergence of events, we not only had one of the best displays of aurora in the past decade, but also the peak of the firefly season and a setting crescent Moon. This photograph was taken facing west in front of our home as the Moon set behind clouds, the aurora flickered in the sky, and fireflies blinked around me. (Canon 6D, 24mm lens at f/4, ISO 2500, 15-second exposure, taken June 23, 2015, at 12:07 A.M. EDT, from Big Bay, Ontario, Canada)
