That after sun glow

The orange, red and yellow glow in the sky after the sun has set is caused by the sun shining on the underside of high altitude cloud. It's reflected in the water and the land is in shadow.

I went to the reservoir in Inniscarra yesterday evening to capture the sunset. It had been a glorious day and I saw there would be a smattering of cloud at sunset, which might make for a dramatic picture.

As it happened, there was cloud, but it was mostly at the horizon in a thick, impenetrable bank. The sun set several minutes too early, with barely a glimmer of yellow, but twenty minutes later I was treated to a spectacular display of colour.

AFAIK, it’s caused by the sun shining through the atmosphere at the underside of high altitude clouds on the horizon. If you use the mobile app, Clear Outside, look for high altitude cloud. If there’s a lot of it, and not much low cloud, you’ll probably have a nice sunset. 🙂
