Lower Tangent Arc on September 25th, 2005

An unusual sight: a fragment of a brilliant lower tangent arc or rather circumscribed halo partly hidden by the clouds - this is why the blue part of the arc is not visible. The solar altitude was roughly 30.5°: The arc was the only halo and came as a suprise in a sky dominated by cumulus and altocumulus clouds. It seems that there was no cirrus. A little later strong iridescence could be observed near the sun. Canon Powershot G6, the focal length corresponds to 122 mm with a conventional 35 mm camera. Processed with Photoshop Elements.
