Cloud iridescence

Yesterday afternoon, I was out in the garden hanging a few clothes on the line, hoping they would get a little warmth from the last hour of sunshine. The sky was clear except for a few clouds, I noticed towards the direction of the sun, but higher in the sky a colourful cloud. I texted John who was returning home on the bus. My camera had a zoom lens,  so I was unable to give the context of the cloud in the sky, but these images show the intensity of colour. It is cloud iridescence (click for info), it gave the impression of a colourful moustache.
