Despite the simplicity of the explanation, the case was recorded by the GEIPAN with a classification B, indicating an observation that cannot be confirmed or rejected with certainty. The description of the object and the context of the sighting do not present clearly unexplained elements, but its official registration raises the possibility that some detail was not immediately recognized.
