We visited Devon about ten years ago and stopped in a caravan site near the sea. We walked down to the sea at sunset on the first day as there was a glorious sunset. Then as we got near the beach and were walking through tall grasses along the path to the beach, I saw this. I was stunned. I knew it was something to do with the sun, that had set. But I had my camera, so I took this photo. I think it’s called a sun pillar. I’ve seen sun dogs since. They are bright spots some way from the sun on either side. And brocken spectre, where your shadow is cast onto cloud by sunlight being you and it creates a sort of glowing rainbow halo. There are many other effects caused by the sun and light from it.
The world is a fascinating place.
