UFO sighted in Chicago in 1965

Summary

In September 1965, a witness in Chicago, Illinois, reported a non-identified object that appeared like a star. The UFO was moving north without making noise and was observed for 25 minutes. Although initially thought to possibly be a civilian satellite, the lack of precise data made evaluation difficult. The report mentions that the object had a bright yellow-green appearance, with an outer stationary circle and an inner circle spinning clockwise. The observation was made from the ground, without optical aids, and the witness described the phenomenon calmly, without appearing excited.

The case was categorized as insufficient for a definitive evaluation, and additional information was requested through a supplementary form. Despite the detailed description of the object and its behavior, no physical evidence or photographs were found to support the sighting. This document is part of Project 10073, an effort to record and analyze UFO sightings.
