A view of a double rainbow with a distinctly visible Alexander's dark band between the two rainbows. The order of the colors in the second arc, when compared to the colors in the first arc, are reversed du to the second internal reflection that takes place in the water droplet in the atmosphere. The image was captured on March 18, 2020 out of the back door of our laser labs in Tucson following a thunderstorm, and was captured in panorama mode with an iPhone X.
