Alejandra Rubio — El Calafate; Province of Santa Cruz

Official source account — 2022 annual report, printed page 6: Alejandra Rubio noticed an elongated blurred object only when reviewing an El Calafate photograph. CIAE examined the shape of its motion trace and considered an insect crossing the camera view during exposure the supported explanation. It classified the case Type B, acknowledging that the accidental short-lived passage could not be recreated or independently witnessed and offering no confirmed species identification. 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.
