You can see the grey cloud in the odd shape with an orange light near the middle.

Experts have since chimed in to say they believe the phenomenon is a ‘vapour mark’ which is around a kilometre in length.

They added the clouds could be the start of a number of cloud formations.

One said: ‘The name for this rare type of cloud is lenticular cloud, this is a stationary lens-shaped cloud that forms in the troposphere, normally in perpendicular alignment to the wind direction.’
