In April 2008, in the San Juan hamlet on the outskirts of Pucallpa (Ucayali department, in the Peruvian Amazon), residents reported that for several nights 'lights' flew over the area and projected beams of light directed at people. The account —gathered by media and local ufology— describes a frightened population that associated the lights with a recurring nightly aggression and experienced the episode as a collective harassment. That feature —lights that are not merely observed but seem to 'attack' people with directed beams— is what leads to comparing the case, on a smaller scale, with the Brazilian Colares episode (1977), where residents of Colares island reported burns and physical effects attributed to nighttime light beams. The comparison is one of phenomenological pattern, not of magnitude or evidential backing: Colares produced a military file (Operation Prato) with photographs and drawings; Pucallpa does not reach that level of documentation.

The Peruvian Air Force's OIFAA (Office for the Investigation of Anomalous Aerial Phenomena), led by Commander Julio César Chamorro, received the report and, according to the sources, already had personnel in the region tracking the phenomenon. The very existence of this office is notable: Peru is one of the few countries in the region to have maintained an official window within its air force to channel reports of anomalous aerial phenomena, and Chamorro is its most visible figure. The civilian component of the investigation was provided by three Communication Sciences students from the University of Lima —Teresa Lucía Chamorro (the commander's daughter), Martha Wong and Luciana Macías—, who took the case as a project for the 'Fundamentals of Information' course, with the support of Chamorro and the office. The students traveled to the area, gathered residents' testimonies and assembled material they would later describe as an experience that transformed their understanding of the phenomenon.

The material gathered was presented publicly at a ufology congress in Lima, where the case was publicized as 'the Pucallpa UFO'. Unlike Chulucanas (2001) or La Joya (1980), the available documentation is comparatively weak: residents' testimonies, local press coverage and outreach work, without an equivalent open, verifiable technical file —no radar, no independent photographic analysis, no robust chain of custody for the material. It is also worth recalling that the Amazonian context introduces plausible prosaic explanations for 'frightening nighttime lights': from meteorological and bioluminescent phenomena to collective suggestion in isolated communities, none of which can be either confirmed or ruled out with the available evidence. It is therefore usually described as an open case, pending a more rigorous analysis.

Pucallpa importa por lo institucional y por su contraste, no por la fuerza de su evidencia. Su valor central es mostrar a una oficina oficial —la OIFAA de la Fuerza Aérea del Perú— recibiendo y canalizando un susto amazónico de 'luces que atacan', exactamente el tipo de reporte folk que en la mayoría de los países no habría dejado rastro estatal alguno. Es, junto a Chulucanas (2001), la otra cara del experimento peruano de mantener una ventanilla militar permanente para lo anómalo: una decisión institucional poco común en la región que el corpus registra como dato sobre el comportamiento del Estado, con independencia de lo que realmente ocurriera en San Juan.

Pero el caso marca también, con honestidad, el piso de calidad del corpus. La pesquisa no fue una investigación técnica de la fuerza aérea sino un trabajo de curso universitario apoyado por la oficina, basado en testimonios de pobladores y documentación secundaria, sin radar, sin análisis instrumental y sin un expediente verificable. La cercanía familiar entre el comandante de la oficina y una de las investigadoras —su hija— añade, además, una nota de cautela sobre la independencia de la pesquisa. Y el escenario amazónico ofrece varias explicaciones prosaicas para luces nocturnas que asustan, ninguna confirmable pero todas más económicas que una hipótesis exótica.

Por eso entra como Tier B y con cautela explícita: es un registro institucional de un fenómeno folk-amazónico, no un caso con sensores. Su función en el corpus es doble: amplía la cobertura geográfica al interior de la Amazonía peruana y, sobre todo, fija de manera transparente el umbral inferior de lo admisible —un caso que se incluye precisamente para mostrar dónde está el límite de la evidencia aceptable—. La comparación con Colares es de patrón fenomenológico ('luces que agreden a una comunidad'), no de solidez probatoria: Colares dejó un expediente militar con material fotográfico; Pucallpa, un susto bien intencionadamente documentado pero técnicamente pobre.

Pucallpa matters for the institutional angle and the contrast, not for the strength of its evidence. Its central value is showing an official office —the Peruvian Air Force's OIFAA— receiving and channeling an Amazonian scare about 'attacking lights', exactly the kind of folk report that in most countries would have left no state record at all. It is, alongside Chulucanas (2001), the other face of the Peruvian experiment of maintaining a permanent military window for the anomalous: an unusual institutional decision in the region that the corpus records as a datum about state behavior, regardless of what actually happened in San Juan.

But the case also marks, honestly, the corpus's quality floor. The inquiry was not a technical air-force investigation but a university coursework project supported by the office, based on residents' testimonies and secondary documentation, with no radar, no instrumental analysis and no verifiable file. The family closeness between the office's commander and one of the investigators —his daughter— adds, moreover, a note of caution about the inquiry's independence. And the Amazonian setting offers several prosaic explanations for frightening nighttime lights, none confirmable but all more economical than an exotic hypothesis.

That is why it enters as Tier B and with explicit caution: it is an institutional record of a folk-Amazonian phenomenon, not a sensor case. Its function in the corpus is twofold: it broadens geographic coverage into the interior of the Peruvian Amazon and, above all, transparently sets the lower threshold of the admissible —a case included precisely to show where the limit of acceptable evidence lies. The comparison with Colares is one of phenomenological pattern ('lights that assault a community'), not of evidentiary strength: Colares left a military file with photographic material; Pucallpa, a well-intentioned but technically poor documented scare.
