A sundog over Bunbury, Western Australia.
Lacunosus, a relatively rare and short-lived cloud formation, takes on the look of a honeycomb pattern of round holes with frayed edges. It is formed when a layer of rising warm air and a layer of cold air come into contact with one another, causing downdrafts that push through the cloud. This classic example was spotted by Alexia's friend, Bob Hunter, near Lexington, Virginia, US.
