Aurora Borealis or Aurora Australis in Colour

Brief

For this contest I would like to see your colour photographs of the aurora, either aurora borealis or aurora australis. I only want genuine aurora photographs in colour, so please no computer wizardry to create aurora-like photographs. Manipulation to bring out detail or improve the colour is acceptable but no composite images where the sky has been added, just genuine photographs of the aurora. I look forward to seeing your images.
