Sam Dobson was aboard the '50 years of Victory,' the world's largest nuclear-powered icebreaker, when he spotted a white rainbow which is also known as a fog bow. With camera in hand, Dobson snapped photographs of the rainbow as the ship approached the rare atmospheric phenomenon. According to Dobson, "At first it just looked like a cloud, but as we got closer it was a solid rainbow, but white. We were so impressed with it we all got off onto a floating slab of ice to take a closer look. It is actually closer than it looks in the pictures." The fog bow appears white because of the miniscule size of the water droplets measuring smaller than 0.05 millimeters which diffract light rather than reflect light like a normal rainbow. A fog bow is also known as a cloud bow.
