Sun Dogs

Treated to a pair of Sun Dogs for about 15 minutes through the train window as we mover westwards on the way home last night. Never a perfect pair as the thin cloud layer was interrupted by larger clumps, but between Reading and Didcot there they were, waxing and waning to my left. At one point the right hand one was hitting a particular cloud with such intensity that it appeared there was a second 'minor' sun in the sky.
