Lorena Mastroeni — Manzano Histórico, Mendoza

Official source account — 2021 annual report, printed page 43: Lorena Mastroeni found an unfamiliar elongated blur only when reviewing a photograph taken at Manzano Histórico. CIAE interpreted its shape as the motion trace of a flying insect crossing the field during exposure. The agency classified the explanation Type B, acknowledging that the brief accidental passage could not be recreated and that the image alone did not provide a detailed 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.
