The transient aurorae/airglow hypothesis suggests the ashen light is caused by unusually high solar activity interacting with the upper Venusian atmosphere.
Notes on verification
Confirmed as an accurate representation of one recognized scientific hypothesis for the Venus ashen light phenomenon, corroborated by multiple independent sources including Wikipedia, HandWiki, BBC Science Focus, and UCLA research pages. However, this is only one of several competing hypotheses (others include lightning and optical illusion), and some observational studies have found no correlation between ashen light sightings and solar activity, so the phenomenon itself remains unconfirmed and contested in planetary science.
