A remarkable sunset could be seen in parts of the UK as crepuscular rays shone across the sky on Monday evening.

Crepuscular rays are beams of sunlight which pass through gaps in the clouds, made more visible by particles such as dust and smoke in the air.

On Monday night, the rays were made more prominent by a narrow train of Saharan dust drifting across the southern part of the UK.

In this photo, taken by Adam Simpkins in Wiltshire, the sunbeams appear to fan outwards - but this is not the case.

If you were to see the sun's rays from space, they would actually look parallel.

As seen in this photo from Monika Saha, the rays seem to shine out from the middle of the sun in a circle.

The rays can be seen during sunset, as in this picture from GRBiker in London, but are also visible during sunrise.

They are most visible during these times because this is when the contrast between light and dark is most obvious.

This snap from Ricky Howitt in Hill Head shows how crepuscular rays are highlighted at dusk - though for Latin-speakers the clue is in the name.

The word crepuscular comes from the Latin "crepusculum", which means "twilight" in English.

Elsewhere in the UK, this shot from Peter Gibbs shows the sun beating through the trees.

Yes, it's from that Peter Gibbs - the former BBC weather forecaster and sometimes chair of Gardener's Question Time on Radio 4.
