Every light on the globe is a documented report. Each file gives you three things side by side: what was reported, the strongest ordinary explanation, and what nobody has settled. You do not have to believe anything to enjoy the puzzle.
House rules
This site takes no side. A person "reported" or "said" something. An instrument "recorded" or "measured" it. Every file carries its best ordinary explanation, including the ones that turn out weak, and every file says what that explanation fails to cover. Solved cases stay in, because they show how a sighting gets made. Nothing here is offered as proof of anything.
Where a case stands
UnresolvedNo explanation has been accepted. That means unknown. It does not mean alien.
ContestedAn explanation exists and serious people dispute it.
ExplainedA solid ordinary cause. These teach the most about how sightings happen.
Field noteSubmitted by a visitor. Screened by AI for relevance and civility, never verified.
What to trust
The case summaries were written by Claude from the public record and can contain mistakes, so treat them as a starting point and follow the links. Evidence and strangeness scores are editorial judgments. Links marked Source or Records go to a specific document or official collection. Archive buttons run a search for the case and may return nothing.
The picture in each file is an illustration drawn from the witness description. It is never footage.
How checked is it?
Each file is labeled Draft, Machine-checked or Verified. Machine-checked means an automated pass matched every sentence to a cited source. Verified means at least two independent sources agree on every sentence. The method is published with the project so anyone can rerun it.
Oumu
Oumu is an AI character powered by Claude. It can steer the globe, open files and argue either side of a case on request. It is told to hold no position of its own. It is a guide and can be wrong.
