Aurorae Highly commended: Aurora Shot from Plane by Ye Ziyi (China) The vivid green aurora swirls over the deep, blue sky and the orange glow of twilight as seen from the window of a plane travelling from Amsterdam to Beijing. The photographer had been expecting an auroral outburst to occur during the flight, so paid for the seat that was best for observing. As well as the strong auroral activity, the photographer was also blessed with a white night making twilight visible on the horizon. Novosbirsk, Russia, 24 August 2016 Canon EOS 6D camera, 20 mm f/1.8 lens, ISO 2000, 3-second exposure
