Unión Soviética (Ucrania).Byelokoroviche · UFO over Soviet missile base
On October 4, 1982, over a Strategic Rocket Forces base near Byelokoroviche (Ukrainian SSR), military personnel reported a disc-shaped object stationary for about an hour, with radio interference. During the event, per the Soviet investigation, the missiles' launch-control panels began a pre-launch sequence on their own for about 15 seconds, with no command, then reset. It is the Soviet parallel to Malmstrom 1967.

Incident
Institutional evidence: multiple verifiable witnesses or official documentation. Three independent axes: the «tier» measures the strength of the evidence; the «probability» estimates how genuinely unexplained the case is —a natural phenomenon can remain unexplained, so it does not equal «non-prosaic»—; and the partition of explanations (below) says what it most plausibly was. So a well-documented case can have a possible hoax as its most plausible cause, and a Tier B is not, for that reason, a hoax.
Part 01
The night in question
On October 4, 1982, a Soviet Strategic Rocket Forces (RVSN) unit —part of the 50th Missile Division, in the Carpathian Military District— stationed near Byelokoroviche, in the Ukrainian Soviet Socialist Republic, reported the presence of a disc-shaped object that remained stationary over the installation, per the gathered testimonies, for about an hour and was observed by a large number of personnel. The base guarded silos for R-12 intermediate-range missiles; one of the witnesses cited in later materials was a young radio operator, Vladimir Matveyev. Alongside the sighting, personnel reported interference in radio communications during the object's presence.
According to the materials of the official Soviet investigation of the phenomenon —compiled during the state UAP-study program (the Ministry of Defence and Academy of Sciences 'SETKA' network) and released after 1991—, during the object's presence the launch-control panels of the base's missiles autonomously began a pre-launch sequence: in the control room, the lamps indicating the missiles' preparation toward their programmed targets lit up on their own and, about fifteen seconds later, the controls reset to their normal position, with no operator entering commands. The subsequent Soviet investigation, per those same materials, found no equipment fault that would explain the episode.
The event was documented up the chain of command and escalated to the central study. It is structurally and almost exactly analogous to the ICBM shutdown/activation at Malmstrom AFB (U.S., 1967) already in the corpus: the same pattern —a stationary UAP over a nuclear arsenal with interference in the weapons systems— reported independently by the two rival superpowers, which shared neither data nor intelligence on the phenomenon. Verification, however, rests on post-1991 Soviet sourcing: veterans' testimonies and SETKA-program syntheses disseminated after the collapse of the USSR, less auditable than a Western FOIA document contemporaneous with the event. That difference in traceability —not in plausibility— is what is reflected in its calibration.

Why this case moved the needle
It is the Soviet counterpart to Malmstrom: the same pattern —a stationary UAP over a nuclear installation with anomalous activation of the weapons systems— reported by the other superpower, independently and through its own state investigation apparatus. What is analytically powerful is the convergence: two enemy chains of command, at the height of the Cold War, with no channel whatsoever to coordinate accounts, recorded the same motif —a light or disc looming over the arsenal and, during its presence, the missiles 'coming to life' for seconds before settling again—. When two observers who cannot contaminate each other describe the same anomaly, the cultural-contagion hypothesis weakens and the real-pattern one gains ground. That is why it weighs specifically for the 'monitoring of nuclear risk sources' pattern.
Its limit, and a serious one, is the source's verifiability. Malmstrom rests on declassified USAF documents and sworn testimony from identifiable officers; Byelokoroviche rests on Soviet materials disseminated after 1991 —SETKA-program syntheses and veterans' testimonies— that are far harder to audit firsthand and that passed through the filter of a state that no longer exists. That asymmetry does not make the account false, but it demands caution: we cannot cross-check the original file as we can with a FOIA release. That is why the case is Tier A for the institutional standing of the record (a state RVSN/SETKA study, not a rumor), but with calibration deliberately attenuated by source traceability.

Distribution of explanations
This case is classified among the model's hypotheses: the bar splits 100% by how much each explanation weighs (the uncertainty is spread across the hypotheses the case supports). Summed across the corpus they produce the comparable partition. It is a different question from the Probability above: that one estimates how likely the case is a genuinely unexplained phenomenon; this one splits which the explanation would be.

Structured analytical judgment, not a calibrated frequency. Forced classification: the mass the evidence cannot assign is spread across the hypotheses the case does support.
