Did you see a 'halo' surrounding the moon on Saturday night?
A 'halo' or ring of light was spotted around the moon shining over Wales last night.
A halo is a white or faintly coloured ring that sometimes appears around the sun or the moon. It's caused by high, thin clouds known as 'cirrus' found at high altitudes and are very common.
How do haloes form?
Haloes need ice crystals in order to form, either from high cirrus cloud or free falling crystals.
The sunlight or moonlight is then reflected by the ice crystals, producing a white halo.
However, if the light rays strike the light at a particular angle, some light may be refracted. In such situations the halo will have a faint colouration.
