Deception Island lights, Antarctica

Argentine, Chilean and British personnel in Antarctica reported a lens-shaped object, and the Argentine Navy issued a communiqué saying it was neither balloon, star nor aircraft.

1965 CE · -62.97, -60.65 · status: unexplained

The account

In June and July 1965 several sightings were logged at Antarctic bases, some with reported interference to instruments. On 3 July personnel at Argentina's Deception Island station said they watched and photographed a manoeuvring object; the Navy's public statement made world headlines.

The sceptical view

Press reports rarely allowed aurora, bright planets or atmospheric effects to be separated from genuine unknowns, and the photographs were never published in a form open to analysis.

The researched reading

Real multi-base reports, but with no published data the classic polar explanations of balloons, planets and mirages cannot be ruled out.

ExplanationWeightWhy
Something known, misidentified40%Antarctic bases launched their own weather balloons, and Venus and Jupiter low on the winter horizon produce colour changes and apparent movement; the communiqué’s denial of these was asserted, not shown.
Genuinely anomalous18%Personnel at several bases from three nations logged an object, with claims of magnetic interference, and a navy publicly said it was none of the usual things.
A known natural phenomenon16%Strong temperature inversions over polar ice create mirages that make planets and stars change shape, colour and position.
Perception, memory or mind8%Isolation and long polar nights make crews primed to see something, and press attention followed quickly.
Secret human technology8%A reconnaissance or research balloon from another nation would explain a slow object seen at several bases.
A poorly understood natural phenomenon6%Auroral or other high-latitude luminous effects are not fully catalogued.
A hoax or fabrication4%Multiple national stations reporting independently argues against a hoax.

Official position: The Argentine Navy issued a communiqué stating the object was neither a balloon, a star nor an aircraft.
