Photo of the Week for May 8, 2015
Even though the current solar cycle is past its peak and activity on the Sun is starting to wane, the occasional northern lights display still pops up. Of course, the high-latitude locations where auroras are most common also experience shorter and shorter nights as the summer solstice approaches. That means that this April 15 image by Saskatoon, Saskatchewan, photographer Colin Chatfield might be among the last of the current season.
Chatfield used a Canon EOS 7D Mark II DSLR camera equipped with a Tokina 11-16mm wide-angle zoom lens set to 11mm and f/2.8 for this 15 second-exposure at ISO 800.
