Fr.: Ceinture de Vénus  

A pink to brownish border above the horizon separating the Earth’s dark shadow on the sky from the sky above it. The Belt of Venus appears during a cloudless twilight just before sunrise or after sunset. It is due to scattered red sunlight in the atmosphere. Also called anti-twilight arc.
