The moment was captured by David Gutteridge, of Sleaford, at about 3.45pm last Sunday, November 6, after visiting his father, Bob.
David – who was born in the town and has lived here for almost 50 years – shared with us a number of photos from the scene.

Double rainbows are formed when sunlight is reflected twice within a raindrop, with one running red to violet and the other running violent to red.
In between the two rainbows, a dark band can be found. This is known as an Alexander's band, after Alexander of Aphrodisias who first described it in 200AD.
