Description
On a clear day you can see almost forever! The tones you see in the sky are easily seen, but often missed. And, if you do see them, what is the cause?
The pink area called the Belt of Venus is a Victorian-era name for an atmospheric phenomenon seen at sunrise and sunset. Shortly after sunset or shortly before sunrise on a clear day, you are nearly surrounded by a pinkish glow called an anti-twilight arch that extends above the horizon. The arch's light pink color is due to scattering of red light from the rising or setting Sun. Blue light, which is at the opposite end of the color spectrum, has shorter wavelengths than red is scattered more by the atmosphere giving sunsets and sunrises an orange-red color. A very similar effect can be seen during a total solar eclipse near the horizon.
The Belt of Venus or pink glow is separated from the horizon by a darker looking layer which is actually the shadow of the Earth on its own atmosphere. This image of the Belt of Venus and the Earth's shadow was photographed off Waikiki Beach on O'ahu at sunrise. You can see a similar set of colors any clear morning or evening looking east or west over a large, flat area with an unobstructed view of the horizon.
The dark line to the left of the palm trees is a stone wall designed to break waves before they hit the beach. The view is looking west from the Hawaiian island of O'ahu.
This image was made with a Canon 5D MKIII and a 105mm zoom lens set at 65mm. The exposure was 1/125 of a second at f/5.6 hand held. ISO 200.
