Norton, Connecticut, [ILLEGIBLE]Date unknown

On the evening of October 5, 1953, a physics professor and planetarium lecturer near Norton, Connecticut was observing the night sky through 7x50 binoculars when a faintly glowing object suddenly entered his field of view. The object was shaped like a crescent or boomerang with curved swept-back edges. It moved in a straight line at uniform speed, covering about 40 degrees of sky in less than four seconds. The witness described it as light gray, with uniform brightness and no trail or flare. He watched it until it disappeared behind his house, noting that the night's exceptional clarity had allowed him to see several deep-sky objects including star clusters and the Andromeda Galaxy.

The witness reported his sighting to the Civil Air Patrol, which forwarded it to the U.S. Air Force. The Air Force initially requested additional details through a detailed technical questionnaire. In his responses, the witness clarified that he had estimated the object's angular size through his binoculars as approximately 0.5 to 1.0 degrees across, and that he had never previously observed a meteor through optical equipment. He noted there was no haze, clouds, searchlights, or other obvious explanation for what he saw.

The Air Technical Intelligence Center concluded that the witness observed a meteor of unusual brightness and size. Officials reasoned that the horn or crescent shape was likely created by the spark trail in the meteor's immediate vicinity as it burned through the atmosphere. They explained that the object's apparent width being larger than its length could be accounted for by an irregularly shaped meteor tumbling and oriented so its longest dimension was perpendicular to its flight path. The angular velocity of approximately 10 degrees per second, combined with other reported details, was consistent with a fast-moving meteor entering the upper atmosphere. The center noted that the witness's surprise at the event, the brief observation time, and his initial inexperience observing meteors through binoculars all contributed to his misidentification of the phenomenon as something extraordinary.
