BRILLIANT evening sunshine combined with a rain shower to produce one of nature's natural wonders in Worcestershire yesterday evening - a spectacular double rainbow.
Here are 10 pictures captured by Twitter users.
According the to the Met Office, double rainbows are often called 'secondary' rainbows, and are formed by rays of light that are reflected inside the rain drop twice.
If you look carefully, you will see that the extra reflection means that the colours in the secondary rainbow are in the opposite order to the first (or 'primary' rainbow).
The secondary rainbow is also less bright because the light is being spread over a larger area of the sky.
The area between the two rainbows is known as 'Alexander's Band', named after Alexander of Aphrodisias, who first described its occurrence in 200 AD.
So now you know!
