A sundown over Morocco One can see two interesting phenomena at once in the picture made in 1994 in Morocco. The green light, and the shape of the sun itself. How did we get a sun disc in the form of a crescent? If you look at the cloudy background behind the sundisc, it looks as if the sun was superimposed over the clouds. Is the sun crescent a trick of a round-shaped cloud? Do really clouds of such shape occur? Unfortunately, I dont have an answer. Make your suppositions, well discuss them. |
