UFO sighted in Dayton 1964

Summary

A civilian physicist reported a UFO in Dayton, Ohio, in July 1964. The object was observed at twilight, with a brightness similar to a second-magnitude star. It moved from north to south, crossing the zenith, and approached Polaris and Arcturus. The observation lasted 45 seconds, and the object faded near the horizon due to haze. Although considered as a possible aircraft, its speed was much faster than usual. No photos were taken and no physical evidence was found.
