ROAST : iridescent cloud 1

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).
