Milky Sky Circumzenithal Arc

Although the cirrus was extensive it didn't show much in the way of halo effects, except for this circumzenithal arc.

There was little sign up the upper tangent arc, which would have been halfway between the circumzenithal arc and the sun

The circumzenithal arc only lasted a few minutes but was fairly colourful. Fortunately the patches of lower level cloud left a large enough gap to see it clearly.
