The Hebei Power Plant Octahedron
In 9 September 2011, near Luannan County, Tangshan, Hebei, China, a solid black octahedron, two square pyramids joined base to base, apparently hovering in clear sky above the smokestack and cooling tower of a power plant in Luannan County, Hebei. This case file covers what witnesses reported, the official narrative, and a two-pass assessment with its evidence tier.
What did witnesses see at Luannan County?
A solid black octahedron, two square pyramids joined base to base, apparently hovering in clear sky above the smokestack and cooling tower of a power plant in Luannan County, Hebei. The footage surfaced on Youku and YouTube within days of the claimed 9 September 2011 sighting, posted by at least two separate uploaders, and was circulating internationally by 16 September 2011.
What is the official explanation?
None.
What did the witnesses think it was?
Circulated as a UFO; no named witness.
Is the Hebei Power Plant Octahedron real? The two-pass assessment
Pass one: a static, geometrically perfect black solid over an industrial site is consistent with a tethered object or a box kite, the leading candidate. Pass two: a structured octahedral object, a less common morphology worth tracking for recurrence, with the modest corroboration that more than one uploader posted footage in the same week. Verdict: Unknown. No official narrative exists; the date and place, stripped from years of reposts, are restored here from the 2011 posting record.
