Pollen corona. Disk of luminous light surrounding the Moon. A corona is an optical atmospheric effect,which in this case has been caused by a high concentration of tree pollen in the atmosphere. Coronas can also occur when light from the Sun or Moon is diffracted by water droplets in a thin layer of cloud. This corona's elliptical shape is thought to be due to the pollen's non-spherical shape. Photographed in Finland | |
