Glorious

This one was going to wait, but I've just been informed that it's been made the Atmospheric Optics Photo of the day, with many thanks to Les at Atoptics.
Taking the morning flight from Stansted to Santiago on a cloudy day meant that the only place to sit in the plane was on the right hand side, opposite the sun, with a good view of the cloud cover below. I got lucky and had a great view of a glory during most of the flight:

This was one of the clearest I'd ever seen with a very nicely defined double defraction pattern. See here for the partial explanation of the glory.
