Photo of the Week for April 14, 2018
As solar activity continues to wane, so does the frequency of northern lights displays. But from time to time, a good show still occurs. And the farther north you are, the more often you’ll get to witness one.
This striking corona-type aurora was captured just outside Saskatoon, Saskatchewan, by Cathleen Mewis, in the predawn hours of May 28, 2017. She recorded the 4-second exposure at ISO 800 with a Canon EOS Rebel T5i DSLR camera fitted with a 11-16mm zoom lens set to 11mm and f/2.8.
