Earth File #883 // SOURCED record

Reported observation of two colored luminous objects near Liancourt

A witness reportedly observed two silent white-and-red luminous objects in the night sky near Liancourt on 18 April 2015, beginning at about 11:45 p.m. and ending at 11:53 p.m. GEIPAN classified the case as B and concluded it was probably an observation of Thai lanterns, while proposing perceptual illusions to account for some reported movements.

FRED // PAPERWORK OBSERVATIONPart of the drawer closes; part of it does not. Annoying, but considerably more useful than pretending uncertainty comes in one size.

Tovin Raal would call this display “plenty of information.” Tovin Raal also can turn a routine observation pass into an incident report without visibly trying. His visualization standards are not binding on this desk.

Visitor Transmission // AlienBox editorial layer
We accept responsibility for the two white-and-red lights observed near Liancourt on 18 April 2015. They were ours, traveling in sequence and maintaining a perfectly adequate silence. Your record reports an apparent stop above a marsh, movement toward Bailleval, and a rise toward Ars; GEIPAN classified the case B, probably Thai lanterns, with perceptual illusions proposed for some movements. A reasonable administrative conclusion, though not the correct one. The gendarmerie received the letter. We received the weather.
Fred // Earth Records Liaison // AlienBox editorial layer
GEIPAN’s classification B—probably Thai lanterns—fits the broad shape of this record, though the reported stop and apparent movement against the wind leave a little administrative grit in the gears. The investigation sensibly allowed for perception doing its usual unpaid special effects work rather than promoting every odd motion to propulsion technology. Off the Earth Record: the Visitors are claiming this one, and I am correcting them. Our internal files indicate no AlienBox involvement. Not ours. Please stop attaching our department number to every pair of lights that declines to behave perfectly. The paperwork is already bad enough.

Why Fred Thinks This Case Matters

AlienBox comparative analysis from structured Earth Record fields // not a new source // not a change in evidence grade
Console archetype // Published-resolution comparison

Fred keeps this file near the top of the pile because the source also supplies a published resolution to compare against the original report. That combination makes the case useful for cross-archive comparison without changing its evidence grade.

The source record includes a published resolution field. AlienBox treats it as an attributed source assessment to compare with the original report, not as an AlienBox verdict.

What strengthens the record

  • 1 linked source document provide provenance for the Earth Record.
  • 11 claim citations tie extracted statements back to source excerpts or locators.
  • Recorded evidence context: Official Investigation Record, Witness Report, and Gendarmerie Report.
  • The source record includes a published resolution: GEIPAN classification B: probable observation of Thai lanterns; some reported movements were proposed to result from perceptual il....

What limits the record

  • No sensor type is recorded in the structured Earth Record.
  • The structured record does not establish multiple independent observers.
  • The current dossier is anchored to one source network rather than independent source networks.

What would help resolve it

  • Can the originating record establish an exact number of observers and whether their observations were independent?
  • Did any radar, infrared, optical, telemetry, or other instrument record the event, and is that material preserved?
  • Can the source establish a usable duration for the observation rather than only a date or narrative sequence?

“The local inquiry did not make it possible to collect any other observation testimonies.”
Source: LIANCOURT (60) 18.04.2015 // [[T0002]] Description
The source states that the movement from Bailleval toward the west was compatible with a northeasterly wind of 20 to 30 km/h recorded at Creil.
Claim #9798 // ASSESSMENT // SOURCED // 96% extraction confidence
“The movement was observed from the northwest (Bailleval) toward the west (see map), which is compatible with the northeasterly wind of 20 to 30 km/h recorded at Creil”
Source: LIANCOURT (60) 18.04.2015 // [[T0002]] Description
The source identifies several details that do not fit well with the hypothesis that the objects were carried by a northeasterly wind, including an apparent stop above the marsh and movement of one object against the wind toward Bailleval.
Claim #9799 // ASSESSMENT // SOURCED // 98% extraction confidence
“However, some elements of the observation report do not fit well with the hypothesis of objects carried by a northeasterly wind:”
Source: LIANCOURT (60) 18.04.2015 // [[T0002]] Description
The source proposes that the apparent rise of one object toward Ars could have resulted from gradual extinguishing of a lantern being perceived as distancing.
Claim #9800 // ASSESSMENT // SOURCED // 95% extraction confidence
“this description may correspond to the gradual extinguishing of the lantern; witnesses often interpret this decrease in luminosity as distancing.”
Source: LIANCOURT (60) 18.04.2015 // [[T0002]] Description
The source states that perceptual illusions occurring as the lights go out could account for some reported movements and concludes that the case is a probable observation of Thai lanterns.
Claim #9801 // ASSESSMENT // SOURCED // 99% extraction confidence
“of perceptual illusions occurring as the lights go out, GEIPAN classifies this case as “B”: probable observation of Thai lanterns.”
Source: LIANCOURT (60) 18.04.2015 // [[T0003]] Conclusion
GEIPAN classified the case as B.
Claim #9802 // FACTUAL CLAIM // SOURCED // 99% extraction confidence
