A glorious double rainbow appeared in the skies over Cambridge to the delight of city residents today (April 25).

Two brightly coloured arcs shone over the city after earlier April showers.

People shared their best photos of the impressive sight on Twitter, as the full bows arched across the horizon.

Alex Yates tweeted: “Absolutely beautiful double rainbow on the A14 near Cambridge. Had to pull over and take a pic.”

While Anna Fee said: “Beautiful #Rainbow and #DoubleRainbow over #Cambridge this afternoon!”

According to the Met Office the double rainbow phenomenon is actually quite common, especially in early mornings or late afternoon when the sun is low.

Secondary rainbows are fainter than the primary ones and nearly twice as wide.

A key feature of double rainbows is that the colour sequence of the rainbow is reversed.

Instead of red, orange, yellow, green, blue, indigo and violet, the colours run as violent, indigo, blue, green, yellow, orange, red.

The Met Offices website explains how the double rainbows are formed. It says: “Double rainbows are formed when sunlight is reflected twice within a raindrop with the violet light that reaches the observer's eye coming from the higher raindrops and the red light from lower raindrops.”

“This means the sequence of colours is inverted compared to the primary rainbow, with the secondary bow appearing about 10 degrees above the primary bow.”
