Summary
[edit]DescriptionGirdle of Venus and Penumbra at sunset Burke St Boulia Queensland P1030291.jpg |
English: The Girdle of Venus, Belt of Venus, or antitwilight arch is an atmospheric phenomenon visible shortly before sunrise or after sunset when a pinkish glow extending roughly 10–20° above the horizon, and highest near the antisolar point, surrounds the observer.
The sunlight refracted by the fine particulates that cause the rosy arch of the Belt hovers high in the atmosphere and persists long after sunset or before sunrise. As twilight progresses, the glow is separated from the horizon by the dark band of Earth's shadow, or "dark segment." The name of the phenomenon alludes to the cestus, a girdle or breast-band, of the Roman goddess Venus. |
