Guillermo Macherione — City of Buenos Aires

Official source account — 2021 annual report, printed page 12: Guillermo Macherione submitted a video of an orange luminous object moving steadily and apparently dropping glowing material. CIAE compared its colour with known sky lanterns using IPACO and checked that its course agreed with the wind. The combined evidence supported a small hot-air lantern carried by the wind. The agency classified this identification Type A; differing date references in the source require retention. 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.
