The transient aurorae/airglow hypothesis attributes ashen light to unusually high solar activity interacting with the upper Venusian atmosphere.
Notes on verification
Accurately describes one of several competing hypotheses for Venus's ashen light phenomenon; well corroborated as a proposed explanation, but the phenomenon itself remains unconfirmed and contested, with some studies finding no correlation with solar activity.
