Last day of Summer, Red Skies and Sun Dogs

Today felt like the last day of summer, certainly in London today, although did not have much chance to enjoy it. By mid afternoon the sky was clouding over from the north west and the journey home on the train was not as spectacular as the other four journeys taken this week. It was an hour earlier and so the sun had not chance to sink .
Monday this week produced the most spectacular red sky I have seen for quite some time. I'm afraid the photo is from elsewhere but it was on this scale, if not better. The next three days were good too but not like Monday where the juxtaposition of the clouds at varying heights produced the impressive sight.
But today, on the train into London between Didcot and Reading we were treated by the classic pair of Sun Dogs. But not only a pair, as again because of the position of the clouds that became the screen that the broken rainbow was being projected onto, split, and the pairs were being divided again, first into two and briefly into three.
Most if not all the other passengers on the train were blissfully unaware of the natural phenomenon happening on the other side of the window.
