Caption:
Panoramic view of The Belt of Venus, a Victorian-era name for an atmospheric phenomenon seen at sunrise and sunset. Shortly after sunset or shortly before sunrise, the observer is, or is very nearly, surrounded by a pinkish glow (or anti-twilight arch) that extends roughly 10 to 20 degrees above the horizon. Often, the glow is separated from the horizon by a dark layer, the Earth's shadow or dark segment. The Arch's light rose (pink) colour is due to backscattering of reddened light from the rising or setting Sun.
