Stunning photos have captured a rare weather phenomenon over Bristol.
During the full moon earlier this week, photographer Adam Karwowski snapped some shots of 'moon dogs' above Lawrence Weston.
Also known as paraselenae, 'moon dogs' are bright spots which appear on one or both sides of the moon and only appear during specific weather conditions.
The Met Office said they are rare and require a near or full moon and a particular cloud type in order to appear in the night sky.
They are a kind of halo and are caused by the refraction of moonlight by ice crystals in cirrus clouds.
Moon dogs can appear on either side of the moon, or on both sides, as Adam's pictures show.
A spokesperson for the Met Office said the photos taken do appear to show 'moon dogs'.
"They’re a fairly rare optical phenomena and you need a near-full moon and some cirrus cloud to increase chances of them occurring," they said.
"Sun dogs are more common due to the consistency of light off the Sun in the day, while moon dogs are rarer because you need both enough light from the moon, as well as the right combination of clouds."
