That pink cloud at the bottom isn't showing cloud iridescence, is it? The flare suggests that it was pretty close to the sun.
More info about cloud iridescence at http://www.sundog.clara.co.uk/droplets/irid1.htm - and info about all sorts of other wonderful atmospheric phenonema.
Clouds like that (high cirrus) should also produce 22 degree halos (at any time of the day) or sundogs and upper tangent arcs (when sun is low in the sky). [Which you get depends on the ice crystal alignment in the clouds.] I highly suggest that you keep an eye out. And the camera handy, of course!
Sundogs can be very colourful - I've been priveleged to see some very nice ones. The one time I've seen cloud iridescence it took my breath away, the colours were so fantastic!
Me, I want to see the cirumzenithal arc. Supposed to be amazing colours.
"Rainbows, Halos, and Glories" by Robert Greenler is *the* book to get, but horrendously expensive. sundog.clara.co.uk is a very good free alternative.
