Germán Castillos — Barranqueras, Province of Chaco

Official source account — 2020 annual report, printed page 108: Germán Castillos noticed six lights in the upper-left sky when reviewing a photograph. CIAE compared them with six bright rectangular openings elsewhere in the frame. Their relative positions and optical-centre geometry matched the expected pattern for multiple internal lens reflections. The agency concluded that the apparent group was produced by those six light sources inside the camera optics 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.
