Circumzenithal arc?

The (part of a) circumzenithal arc (I think!) that accompanied my bicycle ride on the way back home along the right bank of the Salzach, from Rehhof to Urstein. Too bad that I did not have a camera!

(UPDATED on Sunday, 26th September 2010)
Tuesday and Wednesday I got no luck, but on Thursday, 23rd September 2010, the arc was again there and this time I had a camera with me! :) There are two rainbows at each side of the Sun, separated some 20-30°. Here you can see some pictures of the phenomenon:

Rainbow 02 Rainbow 01

Rainbow 03

Does anyone know what it is? I don't really think it is a circumzenithal arc... Might them be sun dogs?
