Diego Ferraris — Banfield, Province of Buenos Aires

Official source account — 2020 annual report, printed page 93: Diego Ferraris discovered an oval, motion-blurred object while comparing three similar photographs; it appeared in only one. CIAE identified two projections compatible with transparent insect wings. It considered an insect accidentally crossing the frame the best-supported explanation. The agency classified the case Type B, preserving the limitation that the short-lived passage could not be reconstructed or independently witnessed. 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.
