What a surprise to see this gorgeous rainbow appear suddenly in the eastern sky very late in the afternoon on the 9th March 2017 while setting up my telescope at the local library.
I only had my point and shoot camera with me so it was a bit hard to focus, but I did manage to capture some images of the brilliant colours displayed.
What’s so interesting about these types of rainbows is the second band of colours that are inside the primary rainbow. It’s not very often that you see this and it’s caused by interference between the rays of sunlight passing in a direct line through the raindrops. However, the optics behind them is very hard to explain even by the experts. No matter what the science is, these rainbows are just so pretty!
The image was taken with a Canon Power Shot G15 camera, the exposure time was 1/640th of a second and ISO 80 on manual focus.
If you would like to find out more about the fascinating optics of rainbows then please go to Les Cowley’s excellent website called Atmospheric Optics at: http://www.atoptics.co.uk/bows.htm
This is just another reason why you should keep looking up at the sky;
As you never know what stunning weather phenomenon will be on show above you :-)
