Probable lunar occultations of Venus, 2020 to 2060. These are calculated by a simple method that may include some near occultations. The blue points represent occultations closer to the moon's ascending node while the red are closer to the descending node. Note the series of five in 2054, which have been checked.

An angle ε is drawn between two straight lines from Earth to the Sun, and from Earth to the planet. This is demonstrated for different positions along circular orbits, both for planets closer to the Sun (where the angle is always less than 90°), and for outer planets (for which the angle can range from 0° to 180°), while distinguishing east and west sides.

Nightglow is since 2022 considered the most likely candidate for the ashen light, visible as bright line along the limb of Venus in this visible light near-infrared image. The surface and its features, like the visible Ovda Regio plateau of Aphrodite Terra as the dark patch, is much less discernible by the human eye, though some people reporting ashen light might be seeing the surface due to higher sensitivity in the spectrum that the surface glows.
