Perranporth Beach Sand Patterns, Cornwall. I've made lots of these images over my 45 years in photography, but this is probably the best.

Aurora borealis, Northern Lights, with Sea Pinks last night at Wheal Coates tin mine, Cornwall, UK. The pink is caused by Nitrogen particles. Could only just make it out with the naked eye, but a camera with long exposure capability brings it out.
