Rainbow Cloud.

On the morning of January 14th, 2007, I was hunting for a daylight glimpse of comet McNaught. I was using a street light to block the sun, when along came a small scrap of cloud. As it got close to the sun, it came alive with vivid rainbow colours and I took this shot. It was forgotten about shortly after when the comet came into view, but now has its chance to shine again. Photo details: Canon 350D, 1/1000th second exposure with an EF 75-300mm lens, ISO 200 @ f-13.
