A bright moon halo caught the attention of many in the West of England on Monday night.
Leighton James, a photographer in Bristol, said: "It's something I have never seen before and thought it looked quite amazing."
A halo around the moon appears when a thin layer of cirrus cloud - which is very high and made up of ice crystals - moves across the moonlit sky.
Refraction of the light by the ice crystals causes the halo to form.
Mr James said he saw it from Bishopston at 23:00 BST and it grew in size as the night went on.
Several photos were taken and shared on social media.
Dowager Countess Bathurst, who lives in Cirencester, said it was "stunning".
Ian Fergusson, BBC Weather forecaster for the West of England, who also snapped a picture from Somerset, said 22 degree lunar halos are caused by the same reason as solar ones.
