Pinamar coastal flash

Official source account — 2016 annual report, printed page 14: Witnesses around Pinamar, Cariló and Villa Gesell reported a strong blue-white flash followed by a sonic boom at about 21:25. CEFAE compared the available video and event characteristics with meteors, proposing a steeply descending atmospheric bolide. The source is inconsistent on the date: its heading and index give 18 May 2016, while the narrative says 18 May 2015. Both date claims are retained rather than silently resolved. 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.
