Río Colorado — Province of Río Negro

Official source account — 2022 annual report, printed page 74: A photograph taken at Río Colorado, Río Negro, on 26 January 2021 showed an unexpected object when the photographer reviewed the image. The enlargement revealed a spindle-shaped body with two sections and translucent projections above and below. CIAE considered these features compatible with a flying insect crossing the camera's view at the instant of exposure. The photographer had noticed nothing unusual in the landscape. Because the fleeting event could not be reproduced or independently corroborated, the insect explanation received Type B status. 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.
