Iridescent cloud

A nice example of iridescence in high cirrus, seen in Leeds, March 2004.

[Dscn7210iridescent/Jpg]

Iridescent cloud [Leeds, 5:23:38pm Tue 23 Mar 2004; Nikon E995 digicam]

Lee photograhed these iridescent clouds between the houses on a walk down our street on a March evening. Within a few minutes they had all turned grey.

Iridescence is caused by sunlight diffracted through water droplets; these clouds are most commonly seen near the sun, in winter and over mountains (well, two out of three isn't bad).
