Short version: Harbour sunrise with sea ice. Fuller description: Aarhus harbour, Denmark, shortly before sunrise today. Thick circular clumps of white ice cover the surface of the dark grey-blue sea: ’pancake ice’. Sky purple-blue with some white clouds. A tinge of orange and pink on the horiuzon. City and docklands skylines in silhouette. The clock face on a skyscraper clock tower glows dark pink in the distance.
