Eventide- 23

Alpenglow!

We have heard about the ‘afterglow’ very often.
The afterglow is an intense red or golden glow of the western atmosphere long after sunset, when most twilight colors might have disappeared.
I was curious to know about the glow seen in the eastern sky after sunset and got this information that I am sharing here, along with my photographs.
This glow is ‘Alpenglow’!
During sunset on clear evenings, the atmosphere around the horizon opposite of the Sun appears as shades of orange and pink. The pink color is due to the sunlight that is shining through denser atmosphere near Earth’s western horizon, and reflecting off the atmosphere on eastern side. This reflection back towards the observer is called backscattering. It creates a pink and orangish stretch near the eastern horizon. The same light is often seen on mountain tops at sunset and hence the term ‘Alpenglow’.

  1. What beautiful skies! I love the graduation in colour in the top one. It’s interesting to know why the sky can look like this and very special when it happens. 🙂

  2. Alpenglow is such a beautiful sounding word of a beautiful time if the day. Many years ago the sky had become pink in colour. There is a lake in our place. The water was equally pink and at the same time birds were singing. It was heavenly.
