The Haleakala Photometer Object (1966)

Around midnight on 11–12 February 1966 an airglow photometer scanning the sky from Haleakala on Maui recorded two bright pulses that matched no star or planet, perhaps one object crossing some 700 kilometres in a quarter of an hour before it vanished into the Earth's shadow. The Condon Report found no missile launch to account for it and filed it as unidentified. This is the record of what an instrument recorded, not a verdict on what crossed the sky.

◆ THE SHORT VERSION

  • The Haleakala Photometer Object (1966) is a reported UAP case in Haleakala Observatory, summit of Haleakala, Maui, Hawaii, USA, Night of 11-12 February 1966, 23:50 and 00:05 HST.
  • An airglow photometer on Haleakala recorded two bright pulses on the night of 11–12 February 1966 that matched no star or planet.
  • If the pulses were one object, the Condon Report reckoned it travelled a nominal 734 kilometres in fifteen minutes before vanishing, perhaps into the Earth's shadow.
  • No missile launch from Vandenberg or Point Mugu fitted the time, and Wright-Patterson suggested a satellite on which information was not readily available.
  • Condon filed the object as unidentified; no person saw it, only the instrument.
  • For this case Fractured Realities holds 1 distinct source and 1 corroborating primary document.
  • The archive grades it L0 · SINGLE ACCOUNT — the archive holds one account of it, from a single source.

Nobody saw it. The object is two spikes on a paper tape. Colorado project scientists picked an airglow survey from Haleakala at random from nights with no moon and little cloud. It had been made around midnight Hawaiian time on 11–12 February 1966, and they wanted to know whether every bright point the photometer swept across matched a star or a planet. Through the 5300 Å filter every star brighter than magnitude +3 matched the atlas except two. The first pulse came at 23.50, low in the east-north-east about ten degrees above the horizon. The second came at 00.05, five degrees higher and four degrees further round. The report calls them Unidentified Bright Objects. If both pulses were one body, it had travelled a nominal 734 kilometres in fifteen minutes. It showed on only two sweeps out of many, which fits something passing into the Earth's shadow.

What is on the record

The source is the Condon Report of 1968, the University of Colorado's Air Force-funded study of UFOs. The case sits in Frederick Ayer's chapter on instruments for UFO searches, as "Haleakala I". Ayer argued that analysts studying airglow ignore star-like spikes as noise, so their tapes could hold objects nobody noticed. A companion case from Haleakala in 1967 was traced to a ballistic missile.

For this one he considered a satellite in a highly elliptical orbit, or the top of a ballistic path launched in a retrograde direction. The project found that no sub-orbital missiles were launched from Vandenberg Air Force Base or Point Mugu until an hour or more after the sighting. The Aerial Phenomena Office at Wright-Patterson Air Force Base suggested "an artificial satellite on which information is not readily available". The report concludes: "The object is thus in the unidentified category." It does not name who ran the photometer. Its angles carry errors of up to four degrees in azimuth and five in altitude.

Why it sits where it does

L0: a single document. An instrument rather than a person recorded the object, so there is no witness to identify. The tier measures sourcing rather than truth. Condon's authors left the object unidentified, with an unlisted satellite as the Air Force's suggestion. What the photometer caught over the Pacific is not resolved here.
