High Quality Content by WIKIPEDIA articles! The Belt of Venus or Venus`s Girdle is the 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 antitwilight arch that extends roughly 10°–20° 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) color is due to backscattering of reddened light from the rising or setting Sun. A very similar effect can be seen during a total solar eclipse.
