On the way back from photographing at Kanangra-Boyd National Park, I spotted this electrical storm. I returned to a lookout over the valley and was able to obtain unobstructed views of this amazing phenomenon. The cloud was illuminated by the electrical activity within it, and appeared as a beacon in the night surrounded by a starry sky.
