A glow above the lunar horizon after sunset or before sunrise, photographed by Surveyor 6 and 7, sketched by Cernan on Apollo 17, and photographed in colour by Blue Ghost in March 2025 (domes, a 'pillar of light'). The dust explanation was tested by LADEE in 2014, which found too little dust. NASA has not published an explanation for the Blue Ghost images.

Plausibility weighs how well an account fits where secrecy hides the documents by design, so missing records never count against it. Strength measures what is documented. Assessed 2026-10-23.
