Bahia Blanca — Province of Buenos Aires

Official source account — 2021 annual report, printed page 63: A Bahía Blanca witness watched and filmed a bright, colour-changing object near the southwestern horizon for about twenty-five minutes. CIAE's Stellarium reconstruction placed Venus roughly five degrees above the horizon at the reported time. No second comparable light appeared in the video. The agency attributed the colour changes to the long atmospheric light path and classified the Venus identification 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.
