Nahuel Aldir — General Roca; Province of Rio Negro

Official source account — 2020 annual report, printed page 31: Nahuel Aldir saw a bright object and filmed it for almost ten minutes, briefly pointing a finger toward its position. CIAE simulated the western sky for General Roca at the reported time. Venus occupied the same low position and was the brightest object in that sector. The agency attributed the apparent colour changes and motion to atmospheric effects and identified Venus in a Type A conclusion. 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.
