Elizabeth Gervasi — San Gustavo, Province of Entre Ríos

Official source account — 2021 annual report, printed page 15: Elizabeth Gervasi noticed a light in several photographs only days after taking them. CIAE compared the suspect feature with the Sun near the horizon. Its position opposite the Sun and equal distance from the optical centre matched an internal lens reflection. The agency concluded that the recurring upper-right light was a Sun-generated optical ghost and classified the case Type A. 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.
