The runner-up image for the Aurorae category of the 2015 Insight Astronomy Photographer of the Year competition.

The Aurorae category is for photos featuring auroral activity - that is, natural light displays in the sky. The most famous aurorae are, of course, the Aurora Borealis (Northern Lights), which can take on many shapes and forms as they are moulded by the Earth's complex magnetic field.

Runner-up of the IAPY 2015 Aurorae category

The 2015 runner-up for the Aurorae category was 'April Aurora' by Kolbein Svensson (Norway), taken in Hitra, Sør-Trøndelag in Norway using a Nikon D7000 camera and 11mm f/2.8 lens, with an ISO of 1250 and a 10-second exposure.

Svensson told us: 'I really like that we can see the light from the Sun on the horizon. I’ve never seen the aurora so bright at this time. It was taken just after midnight, when the nights in central Norway start to get really bright.'

Our competition judge Melanie Vandenbrouck described it as 'a picture about colour, as much as it is one about the Sun’s particles breaking into our atmosphere. It shows a fantastic spectrum, from sunset to aurora, framed between the black silhouette of the mountains and the darkness of the cosmos.’
