This was taken in Loas at work about 1630 one afternoon, before a thunderstorm, only had small digital camera,( olympus C150) canon 350d at camp, always the way.
Was awsum to watch it change colours and shape, never before seen this display of light and colours.
Wow, sort of a mixed up rainbow effect..cool. Found this website that might explain what it is Iridescent Clouds Good thing you at least had your little camera with you to get a shot!
