The Belt of Venus, also called Venus's Girdle, the antitwilight arch, or antitwilight, is an atmospheric phenomenon visible shortly before dawn or after dusk, during twilight. It is a pinkish glow that surrounds the observer, extending roughly 10–20° above the horizon. It appears opposite to the afterglow, which it also reflects.
