Incredible time-lapse of the cloud path

Beautiful view of the clouds above the sunset, a mixture of cirrus clouds and chemical trails. Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus, meaning a ringlet or curling lock of hair. On planet Earth, cirrus generally appears white or light grey in color. It forms when water vapor undergoes deposition at altitudes above 5,500 m (18,000 ft) in temperate regions and above 6,400 m (21,000 ft) in tropical regions.
