Gatlinburg Double Rainbow
December 12, 2007
The photo above shows a haughty double rainbow that graced the skies over Gatlinburg, Tennessee, as the Sun was setting on June 8, 2007. It was captured from the back deck of my house -- with the camera facing toward the antisolar point (opposite direction from the Sun). Although it is rather bright in this case, a secondary bow is always fainter than the primary (inner) bow. This is partially due to the fact that sunlight is somewhat extinguished by a second reflection within the raindrops. Note that its colors are reversed from those of the primary bow. The secondary bow is also almost twice as wide as the primary rainbow.
