Gisell Tarli — La Plata; Province of Buenos Aires

Official source account — 2021 annual report, printed page 27: Gisell Tarli photographed a passing commercial aircraft and noticed an additional blurred shape at the right edge only afterwards. CIAE found an elongated defocused trace with faint paired symmetrical projections. It considered these compatible with an insect crossing the camera view during exposure. The agency assigned Type B, retaining the limitation that the fleeting accidental capture 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.
