| Greenland Subsun ~ Imaged by Stefan Kuna. ©Stefan Kuna, shown with permission. The subsun is a direct reflection of the sun from millions of plate shaped ice crystals in a thin lower cloud layer. It followed the aircraft as it passed over SW Greenland  . Below are glaciers flowing from the Greenland ice cap. The cap is second only to Antarctica in size and in places is up to 3km (1.8 mile) thick. |
