Today the weather is fine but the wind is very strong, and there is smog. It becomes difficult to photograph the setting of the sun by the sea. Link to the video of the inferior mirage formed when the sun sets: https://www.youtube.com/watch?v=A_lVmY5vO0A. There are several interesting parts in the film. The first is the moment when a mirror-like inferior mirage emerges from the sea level. After that, the sun and the virtual image below are connected together like threads, and the Ω sun is formed finally. After the sun fell below the sea surface, "flash" could still be seen above the sea surface. It was supposed to be green flash, but it turned yellow-orange flash due to the smog.
