José M. Fernández — Punta Alta, Province of Buenos Aires

Official source account — 2020 annual report, printed page 4: While filming a radio-controlled model aircraft, José M. Fernández recorded two small objects that seemed to disappear behind the horizon. CIAE found that their size changed little and that they descended in front of the distant landscape, becoming hidden against dark ground. Their trajectories and proximity supported a pair of insects crossing the camera view. The agency classified this as a supported conventional explanation, Type B. The summaries distinguish reported observations from the agency’s proposed explanations. Source Type A/B ratings describe explanatory confidence and are not encounter classes. The map uses an approximate GeoNames locality centroid, not the observation point.
