The photo shows the setting sun, severely flattened by stratified layers of air at different densities caused by the uneven mixing of a new cold front with a much warmer lingering mass. As the Sun was setting over the sea, it was gradually distorted by differential refraction and acquired many different shapes, including: mushroom, pancake, disk and finally a very thin rectangle. It was indeed a delightful treat to end the day. Note the dark streak at lower left of the disk that actually corresponds to the distorted image of three sunspots of Active Region 2778.
