Paracelsus C structures
A 2016 paper by members of the Society for Planetary SETI Research described two wall-like features on the floor of Paracelsus C, a far-side crater, measured from Apollo 15 and Lunar Reconnaissance Orbiter frames. Later tellings add algorithms that rate the shapes as unnatural. This is the record of what was published and claimed, not a verdict on what the shapes are.
◆ THE SHORT VERSION
- Paracelsus C structures is a reported UAP case on the Moon, analyzed and published 2015–2016 by SPSR.
- The tellings describe building-sized right-angled and T-shaped structures on the crater floor, about thirty metres tall and eighty to one hundred and twenty-nine metres long.
- A fractal analysis is said to rate them the least fractal things in the frame, which the telling takes as a sign of artificial origin; a second telling has bright mounds that respond to detection software the way buildings do.
- A 2016 paper by Carlotto, Ridge and Sirisena measured the two features at 129 and 77 metres long, between roughly nineteen and thirty-one metres high, from Apollo 15 and Lunar Reconnaissance Orbiter frames.
- The paper's authors said the features may be artificial but that imagery alone cannot settle their origin; the ordinary reading is impact ejecta under low sun.
- For this case Fractured Realities holds 2 distinct sources and 1 claimant on its resolved list.
- The archive grades it L1 · SINGLE CHANNEL — it is retold more than once, but everything traces back through one channel.
Counts are resolved totals of what sources say, computed 2026-10-03; the reported details above are claims in the record, not findings. A record of reports, not a verdict on what happened.
