Noctilucent clouds over Champfleurie
Worth checking each night in summer when it's clear to see if there are any noctilucent clouds making an appearance.
They are tenuous cloud-like phenomena in the upper atmosphere of Earth. They consist of ice crystals and from the ground are only visible during astronomical twilight in latitudes 50 - 70 and are at around 80 km high.
Keep your eyes peeled night owls!
