It was about 5 years ago when we were on holiday in Devon. We had arrived at the camp site late in the evening after a leisurely drive down from the Midlands.
As the Sun started to set we walked down through the dunes to the beach. My eye was taken by a pillar of sunlight shining from below the horizon where the Sun had just set. I have seen sundogs before (reflections off clouds on either side of and above the Sun that look like tiny parts of rainbows). But I did not know what this was. Luckily I had my camera with me and snapped these shots.
I later found out this was a sun pillar, caused by the sun reflecting off high icy clouds. I’ve never seen another one.
