Choy attributes recordings of unusual aerial appearances at Chulucanas to several separate episodes.
Chulucanas sightings
Case summary
Anthony Choy attributes recordings of lights near Chulucanas, northern Peru, to 13 and 25 October and 15 November 2001. Participant account.
Chulucanas presents a documentary problem before it presents an image-analysis problem: which recordings entered the inquiry, and which conclusions addressed them? The conflicting inventories and dates make that correspondence central to any account of the investigation.
Choy's account describes investigating the recordings and preparing a field report.
A NUFORC submission and archived video player make the reports and recordings available for wider examination.
Chamorro gives a retrospective interview about the recording procedures.

The reported recordings
Choy’s first account describes investigation beginning in February 2002 and an April field report. Updated in October 2005, it appeared online in October 2006. Its two small still derivatives lack usable exposure or timing data. Account and reproductions.
The stills preserve a published appearance without resolving distance or movement. Examination needs the sequence from which they were taken, the camera behaviour and a reconstructable viewing position. An isolated reproduction cannot show which apparent features persist across frames.
Investigative handling
In a 2014 interview, retired Peruvian Air Force colonel Julio Cesar Chamorro Flores, a cofounder of its Office for Investigation of Anomalous Aerial Phenomena (OIFAA), recalls preliminary assessment followed by Choy’s visit and return with two recordings. His account begins with a call about a municipal employee’s filming. He describes site visits and enquiries to air traffic controllers. His A1 category is a reliability classification for the informant and information, preceding further inquiry. He says they jointly presented Choy’s report to Air Force leadership before his departure at the end of 2002. Procedure and case example.
Chamorro describes a route from preliminary assessment to field inquiry and leadership presentation. Its value is procedural: his recollection explains how the case was handled. The missing report would show what tests followed that initial assessment and how their results were interpreted.
El Comercio’s 2023 retrospective names Iván Iza Nanfaro as the filmer of red and orange lights and describes an 84-page report submitted on 19 November 2002 and an inventory of three videos. It gives 13 April 2001 in one passage and October dates elsewhere. Relevant case passage.
The different inventories could represent different stages, but that explanation needs documentary comparison. A field report and a later submission likewise should not be combined into one undated document. Preserving the discrepancy keeps the research question visible: which material was available at each stage, and which assessment addressed it?
Public circulation and archival survival
A February 2003 NUFORC submission links to a television report rather than supplying firsthand testimony. A 19 February archived Panamericana player page preserves the historical media pointer but no case transcript; the recording itself is unrecovered. Submission and player page.
The archived link distinguishes broadcast circulation from source-film custody. A recovered programme could reveal editing and attribution, while comparison with the source recordings would establish what the broadcaster received and changed.
The newspaper reports a 2004 computer theft affecting investigative material. Institutional history.
The loss account leaves several custody routes worth tracing: the filmer’s originals, investigative copies, broadcast material and recipients’ copies of the report. Their survival must be checked individually.
Later observations and competing interpretation
Choy describes his own lights in February 2003 and a separate 2004 television-team visit, with camera/visual detection interpretations. Part 1 and Part 2.
Roy’s October 2009 post recounts an August visit, during which he attributes observed lights to residents’ flashlights, fires and distant traffic. He expressly leaves the wider claims unsettled by one visit. Complete visit account.
Roy’s observations offer scene-specific alternatives to test against an identified recording. Their relevance depends on matching direction, time and scene. The same comparison is needed before later unusual appearances can strengthen the earlier account: geography alone does not establish continuity.
Evidence assessment
The inconsistent published counts make the submission inventory central to Chulucanas. Until the material examined by investigators is matched to the filmer’s originals, a reliability grade or later interpretation may concern a different selection of images. Comparing dates, exposures and custody would distinguish added material from different counting practices or changes in recollection.
The ordinary local lights identified during Roy’s later visit supply candidates that can be tested against particular sightlines. A later-night resemblance is weaker than correspondence in bearing, duration and scene position for an original exposure. Camera movement, focus and reproduction also need to be examined through the native sequence; a small published image cannot determine whether its unusual appearance belongs to the source or the acquisition process.
Separate observations grouped under the same case name may create apparent accumulation without a continuous evidential chain. Conversely, a consistent inventory and independently matched observations could constrain that explanation. The useful next comparison is therefore between original records and specific scene or imaging models, rather than between general claims that the area’s lights were ordinary or extraordinary.
Open questions
Which recordings entered the investigation?
A dated inventory would connect individual exposures to the report that assessed them. This would determine whether different counts refer to different stages.
How were the reported dates recorded?
The earliest statement, programme caption and submitted report should be compared before choosing a calendar date. Publication errors and differing episodes require different resolutions.
What did the assessment actually conclude?
The original reasoning would show whether the inquiry judged testimony, image quality, a conventional explanation or physical identity. Those propositions cannot be substituted for one another.
Further research
Witness record
El Comercio identifies Iza Nanfaro as the filmer. Case passage.
Choy supplies participant investigation and later observation accounts. Accounts.
Chamorro supplies procedural and presentation testimony. Interview.
Roy supplies a later visitor’s observations. Post.
These roles differ from an original filmer’s exposure-by-exposure statement. Institutional participation and later observation should retain their own dates and evidential functions.
