Juerg Alean's image demonstrates that fogbows, like rainbows, are complete circles and centered on a point directly opposite the sun, his shadow marking the centre is weakly visible on the ship's wake. This fogbow is diffuse with faint straw and red colours on the outer rim. There are no supernumeraries suggesting that the fog droplets had a wide range of diameters, a characteristic of "old fog" where the droplet population has had time to evolve by condensational growth, merging and splitting.
