Liliana Acosta storm photographs

Official source account — 2017 annual report, printed page 16: Liliana Acosta photographed an approaching storm at Villa Urquiza, Entre Ríos, on 27 February 2017. She noticed dark points in the pictures the following morning, although nobody had seen anything unusual in the landscape. CEFAE identified a central body and blurred translucent wings at the limit of the image's detail. It interpreted the marks as an insect that crossed close to the camera and appeared in two frames. 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.
