Interesting, cloud formation in the sky! The dark grey, yellow, blue, white and peach colours of the mid-winter sunset in the sky, as well as the contrail from an airplane over Cottenham, UK add to the dramatic picture just before the sun goes down at the end of another long day. The dark grey clouds look like a long, bumpy road! From Rebecca Hill, Canberra, Australia
