Sunshine and shadow

The sun played hide and seek all afternoon. There seemed to be a pinkish tint on some clouds - an optical illusion, though not as dramatic as the iridescence I photographed in July 2008.

Love the iridescent clouds, and especially the linked image from July 2008. Spectacular and beautiful!

Thanks Robin. My son saw one on his travels in Cambodia - he changed the caption after I identified it: Iridescent pileus cloud.

Love seeing photos of iridescent clouds in Cambodia! Wonderful.

When I saw my first iridescent clouds, I always called them sundogs. Here's a link to some not-very-good photos I took when we first moved to Grass Valley. I called them sundogs.

Robin, I can't see your link.

A sundog or parhelia is a particular type of iridescence. There can be two of them, one on either side of the side, at the same elevation. Sometimes there's only one, depending on the clouds. It's a bright spot of light, rather than a sheet. See my Flickr set for more about them.
