PHOTOS: IAN GRIFFINOne of the sheer joys of stargazing in this part of the world is spotting an aurora australis glowing in the southern sky. Different glowing gases cause different auroral colours. I’ve managed to photograph the Southern Lights on more than 200 separate nights since moving to Dunedin in 2013. With increasing auroral activity in mind, it seems timely to share a guide to the different auroral forms. Occasionally seen in isolation, auroral patches can form in parts of the sky well away from the main display.
