We got off a train at Cradley Heath having been for a night out in Birmingham and this was how the sky looked from the railway bridge.
These clouds are rarely seen as they are mostly gathered around the poles of Earth, but this night they were seen as far south as Paris and Italy. When we got home these were 2 pictures I took with my phone.
The origin of noctilucent clouds is very much a matter of study. They are known to be over 80km (50 miles) above the surface of the Earth. They have been studied from the International Space Station. More information on Wikipedia.

The clouds were due North and the sun was about 12 degrees below the horizon in Astronomical twilight.
