Well I was jogging with a full hiking pack through the bush (to get to my destination before the sun went away), and came up to a ridge clear of trees where I could see this view. The sunbeam in the gap of the clouds lasted about 90 seconds, enough time for me to change lenses, then faded while I watched. If I were a couple minutes faster or slower, I would have just seen a drab grey skyline. Happy little accident.
