Diego Echeverria — Mina Clavero; Province of Córdoba

Official source account — 2021 annual report, printed page 70: Diego Echeverria noticed an unusual object only when reviewing a video from Mina Clavero. CIAE examined a body with two symmetrical projections near its front third and interpreted the shape as a flying insect turning sharply in front of the camera. It classified this as a supported Type B explanation, while retaining that the accidental passage could not be recreated. 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.
