Weak Circumscribed Halo

One of the more colourful haloes this year with the colour suggesting it was the upper tangent portion of a circumscribed halo. The sun was 62 degrees above the horizon.

(The image isn't vertical so a horizontal line from the sun lies at about 4 oclock)

The circumscribed halo is clearly visible as an extra arc to the lower right, just outside the normal 22 degree halo.

The full pair of haloes didn't last long and a few minutes later only this lower tangent arc was left.
