Colours of Contrails (twice in a row!)

It happened again! A few days back, on 19th July, I captured iridescent contrails for the first time. This morning, while I was taking a walk on my terrace, I noticed an incomplete 22° solar halo. This made me think about some possibilities of optical phenomena. I waited for another hour in the sun and was able to capture two Biman Bangladesh flights with iridescent contrails. The colours were more vivid and varied than the last instance.

Hope you enjoy the colours.
