CIA-UAP-D001, Intelligence Information Report, USSR, 1973
This document is a Central Intelligence Agency (CIA) intelligence information report (IIR) that describes human intelligence gathering activities in the Union of Soviet Socialist Republics (USSR). This report characterizes its content as informational, not as finally evaluated intelligence. In section 14 of this document, the source describes an incident occurring in summer of 1973, where he allegedly observed an airborne, luminous, bright green, unidentified object. The source described concentric circles forming around the phenomenon over a period of several minutes, before it dissipated. The source also stated that no sound attended the observation. The source offered no opinion on the nature of the phenomenon and was unable to provide further details regarding the incident.
The summary above is sourced from the released file metadata as published to war.gov. The analysis sections below are original to this tracker.
Where this file fits in the PURSUE archive
This file is one of CIA's 21 files in the Trump PURSUE disclosure. Within the CIA agency block it ranks #21 of 21 by Anomalousness Index. Across the entire 334-file archive it ranks #329 of 334.
That places it in the lower-scoring band of the archive (329 of 334 by score), typical of investigative-record style files where the report is paper-based rather than instrumented.
For the broader cluster context, this file is part of CIA-UAP-D001 (1973 USSR) - the 1973 CIA Intelligence Information Report describing a HUMINT source's observation of a bright green airborne UAP in the Soviet Union. The cluster page walks through all 1 member files with regional grouping, sensor breakdown, and standout analysis.
Anomalousness Index: 47/100
Evidentiary weight that this encounter remains unexplained after conventional analysis. Not a probability of extraterrestrial origin - that number is not honestly computable from the released files and this tracker refuses to publish it.
🤖 AI-ASSISTED SCORING · methodology
The six rubric components break down for this file as follows. Each component has a weighted contribution to the final score; the per-component explanation below describes what this file's particular value on that component means in the rubric's framework.
No sensor, camera, or instrument backs this observation - it is testimony, relayed through the CIA, and scored on the rubric's lowest sensor-quality tier for that reason. That doesn't bear on the witness's credibility (a separate axis); it reflects only that nothing beyond human perception recorded the event.
A civilian account, routed into the federal record via the CIA's investigative channels rather than an operational mission report. The rubric scores this tier below uniformed personnel specifically because of that remove - the witness wasn't reporting from within a federal mission context when the observation occurred.
On corroboration, this file from the CIA - like every single-tier file in the PURSUE archive - is a single-witness or single-instrument capture per the released metadata. The rubric doesn't infer multi-witness confirmation the summaries don't actually establish; this score reflects the honest limit of what was released, not a judgment about the underlying event.
The released file contains no speed, acceleration, or vector data precise enough to score on the kinematic axis - and that's true archive-wide, not specific to this file. The rubric declines to infer kinematic anomaly from a witness's narrative estimate of how fast something moved; that itself says something about what PURSUE actually released: descriptive accounts, not flight-path telemetry.
Every file in the archive, including this one, scores this tier: a conventional explanation was considered in the released record but isn't treated as dispositive. That's a pattern in how war.gov's own summaries are written - they consistently hedge against strong conclusions either way - and the rubric takes that hedging at face value rather than resolving it for them.
This file from the CIA is catalogued as unresolved, with no formal review process having concluded - logged into the system, but not yet finalized by any review. The rubric treats that differently from 'open after review,' because the absence of a completed review is itself part of the file's status, not a placeholder for one.
Bottom line on the score: the Anomalousness Index of 47/100 reflects evidentiary weight that this specific file's encounter remains structurally unexplained by the rubric's six axes - it is not a claim that the underlying event involved anything non-conventional, and it is not comparable across rubrics that use different weights.
