Simón Bustos — Sierra Colorada, Province of Río Negro

Official source account — 2020 annual report, printed page 164: Simón Bustos captured a bright phenomenon in two twenty-second astronomical exposures at Sierra Colorada. CIAE and external orbital specialists matched its path and stellar background to a Long March 8 rocket launched from Wenchang approximately fifty-three minutes earlier. The agency attributed the unusual appearance to the rocket's ascent-related activity and recorded a Type A conventional identification. 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.
