At night under a clear sky the ground radiates heat away to space.The surface cools and this in turns cools the adjacent air to form a radiation fog.If there is a bright enough moon then a lunar fogbow might be visible.
It was a stunning optic phenomena to witness as if you move the fogbow moves with you, so it has been easy to set up a composition with that tree ;)
