Sonia Albelo — Provincial Route 34, Km. 48, Province of Córdoba

Official source account — 2022 annual report, printed page 81: Sonia Albelo noticed an object while reviewing a photograph taken near kilometre 48 of Provincial Route 34, Córdoba, on 8 October 2021. Enlargement and increased contrast showed a white central body strongly reflecting sunlight, with two translucent elliptical projections. CIAE proposed a flying insect that crossed the field of view unnoticed at exposure. The absence of a visual sighting supported that interpretation. Its fleeting nature prevented reproduction or corroboration, so the official insect explanation was classified 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.
