TL;DR
A Soviet military facility worker at Sary Shagan — the USSR's primary BMDS test range — observed a silent green luminous object forming concentric circles for several minutes in summer 1973. The CIA collected this as HUMINT and filed it December 20, 1973; it became the first document in the CIA UAP intelligence series upon PURSUE Release 2 declassification in 2026.
Confirmed
- ✓CIA-UAP-D001 is a genuine CIA HUMINT intelligence report, confirmed authentic via PURSUE Release 2 (war.gov/UFO, May 22, 2026)
- ✓Location confirmed as Sary Shagan Weapons Testing Range, Kazakhstan — the Soviet Union's primary ballistic missile defense test site
- ✓Object described as bright green, luminous, and airborne with concentric circles forming over several minutes; silent throughout
- ✓Collection period November 1972 to November 1973; incident summer 1973; report date December 20, 1973
- ✓Source was a former Soviet citizen who served at Sary Shagan — HUMINT with direct facility access
Unresolved
- ?Whether the object was related to Soviet missile test activity, atmospheric events, or plasma effects from high-energy experiments at the range
- ?Witness identity (redacted in the CIA report)
- ?Precise date within summer 1973
- ?Duration and trajectory of the object beyond the concentric circle formation phase
- ?Whether any Soviet records of this incident exist in post-Cold War declassified archives
Strongest mundane explanation
Sary Shagan hosted active Soviet ballistic missile and anti-ballistic missile testing in 1973. High-energy radar systems (including early Hen House and Dog House phased-array ABM radars) were operational at the range. Electromagnetic plasma effects, ionization events from high-power radar emissions, or misidentified reentry vehicle reentry signatures could produce a green luminous airborne display with apparent concentric ring structures. However, the sustained multi-minute duration and the witness's explicit silence observation make a brief kinetic or plasma event a weaker fit.
During the summer of 1973, a former Soviet citizen serving at the Sary Shagan Weapons Testing Range — the USSR's primary ballistic missile defense test site in Kazakhstan — observed a bright green, luminous airborne object that formed concentric circles over the course of several minutes before disappearing. The witness reported the object was completely silent throughout the observation and offered no opinion as to its nature. The incident was collected as HUMINT by the CIA during the November 1972 to November 1973 collection period and formally reported on December 20, 1973, becoming the first document in the CIA's UAP intelligence numbering series (CIA-UAP-D001) upon declassification via PURSUE Release 2 on May 22, 2026. The green color signature and proximity to Soviet nuclear-capable military infrastructure directly parallels the contemporaneous U.S. Green Fireball Phenomenon observed at nuclear facilities in New Mexico during the same Cold War era.
Key Facts
- ›Sary Shagan Weapons Testing Range: the USSR's primary anti-ballistic missile test site on the western shore of Lake Balkhash, Kazakhstan
- ›The facility hosted Soviet ABM radar systems (Hen House, Dog House series) and ballistic missile defense interceptor testing throughout the 1970s
- ›Object: bright green, luminous, airborne; formed concentric circles visible over several minutes; silent throughout
- ›Source: a former Soviet citizen with direct Sary Shagan facility service — HUMINT collected by CIA, November 1972 to November 1973
- ›CIA report dated December 20, 1973; designated CIA-UAP-D001 upon PURSUE Release 2 declassification (May 22, 2026)
- ›Green color signature is the same anomalous characteristic documented at U.S. nuclear facilities in New Mexico (1948-1952 Green Fireball Phenomenon)
- ›The source offered no opinion on the nature of the object — consistent with a careful HUMINT source, not an embellished account
- ›The document was classified from 1973 until PURSUE Release 2 in 2026 — 53 years of suppression
