A very low rainbow. At the time of the shooting, the Sun was almost 35 degrees above the horizon. If the Sun was low, the rainbow arc would have been high. If the Sun has an altitude greater than approximately 40 degrees, the rainbow is below the horizon, therefore cannot be seen. The shot is taken at Athens Olympic Stadium.
