As I was clearing away my stuff at the end of the day I noticed a corona around the sun. They once had mystical significance. The effect is produced by light refracting through millions of ice crystals. If you and I stand side by side, as close as we can get, we will still see a personal halo, because we will be viewing it through different crystals.
It's not the best photograph of a corona, the light was changing fast and I barely had time to grab my camera before it disappeared
