Ashen light is a subtle glow that has been reported by observers on the night side of the planet Venus.
Notes on verification
Confirmed by multiple independent astronomy sources (JBAA, BBC Science Focus, Sky at Night Magazine, Wikipedia) that observers have reported this glow since 1643. The claim only asserts the observation/report history, not that the phenomenon is scientifically proven or physically real, which is an important distinction upheld by all sources.
