Due to cold conditions, three suns were seen in Mongolia. This phenomenon, a rare optical illusion, is known as anthelion. Only the middle sun was real, and the other two on the left and right were the reflections. The temperature must be below -30C for this condition to occur. It was explained that the reflection is seen when the sunshine in the sky and the light passes through the snow crystals when they are suspended in the air. The air needs to have clouds and vapor at the same time. They can be seen anywhere in the world but they are not always obvious or bright. This phenomenon is the best seen and are most visible when the position of sun is low.
