The above photo showing a faint moondog was taken from Quimper, Bretagne, France on the night of August 28, 2004. As I glanced up at the sky, I noticed a dim patch of light to the right of the Moon and quickly set up a tripod for my digital camera. When the Moon is full or nearly so and cirrus clouds (composed of hexagonal ice crystals) are positioned in the sky in the Moon's vicinity, halos and their kin can occasionally be seen by keen eyed observers. The optics are the same as during the daytime -- the only difference is that the nighttime light source is considerably less brilliant.

Photo details: Camedia 5060, 100 ASA, 30 sec.
