Explanation: If your sister-in-law phoned you at 1am to tell you there was a circle around the Moon, how would you react? When it happened to him early last Sunday morning, photographer Laurent Laveder, grabbed his equipment and ran outside! He was rewarded with the sight of a bright lunar halo shining in his neighbourhood skies above Quimper, France. With a radius of 22 degrees, the beautiful halo is produced by the refraction of moonlight in hexagonal-shaped ice crystals formed in thin, high clouds. Laveder captured a series of digital images that he used to create this composite fisheye view as well as a remarkable 360 degree VR panorama.
