Natalia Giraldez — City of Buenos Aires

Official source account — 2020 annual report, printed page 97: Natalia Giraldez filmed lights over Buenos Aires at about 19:08, while a neighbour described an earlier crossing formation. CIAE ran two Orbitron simulations. They indicated that she saw the end of one Starlink train and that the neighbour saw it cross a more compact train travelling on a different heading. Paired satellites in the latter produced a zigzag impression. The agency assigned 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.
