The lunar horizon glow

Surveyor landers in the late 1960s photographed a glow along the Moon's horizon after sunset, and in December 1972 Eugene Cernan sketched streamers rising above the limb from Apollo 17's orbit. A telling in the archive says NASA's later mission ruled dust out. This is the record of what was observed and claimed, not a verdict on what makes the horizon shine.

◆ THE SHORT VERSION

  • The lunar horizon glow is a reported UAP case in lunar orbit, December 1972.
  • From Apollo 17's orbit Eugene Cernan sketched a glow on the Moon's horizon with streamers rising above the limb, on a world with no air to scatter light; the telling puts the streamers at equal spacing and some 120 kilometres.
  • Surveyor probes on the surface had earlier seen a dome-like glow above the horizon after sunset; Surveyor 7 photographed it in January 1968.
  • The telling says NASA's LADEE mission and laboratory studies ruled dust and gas out; the public account runs the other way, with electrostatically lifted dust still the explanation of record.
  • LADEE in 2013 and 2014 found a dust cloud around the Moon but saw no rays of the kind Cernan drew, and what its camera saw at the horizon was zodiacal light.
  • For this case Fractured Realities holds 1 distinct source and 1 claimant on its resolved list.
  • The archive grades it L0 · SINGLE ACCOUNT — the archive holds one account of it, from a single source.

The Moon has no air to scatter light, so a glow on its horizon after sunset needs explaining. The archive's single telling puts two observations together. Surveyor probes on the surface saw a dome-like glow above the horizon after sunset. Apollo 17 astronauts in orbit, with Eugene Cernan as the named witness, saw the glow with equally spaced streamers reaching some 120 kilometres. The telling says the dust and gas explanations were later ruled out by NASA's own LADEE mission and by laboratory studies.

What is on the record

A single claimant, Cernan, on one video and one channel, with no documents. The record spans the 1960s and 1972 rather than a night.

Outside the archive's holdings both observations are real. Surveyor 7 photographed a low horizon glow in January 1968, and Cernan's sketch pad from lunar sunrise, with its glow and linear streamers, survives in NASA's archive. The explanation of record is electrostatically lifted dust, with zodiacal light and the solar corona behind it. The telling's claim that LADEE ruled dust out runs the other way from the public account: LADEE in 2013 and 2014 found a dust cloud around the Moon but saw no rays of the kind Cernan drew, and what its camera did see at the horizon was zodiacal light. The question is open, not closed the way the telling says.

Why it sits where it does

One account, so L0, though the two observations inside it are NASA's own and only the reading of them belongs to the telling. What the streamers were is not resolved here.
