AI-Generated Summary
An object found by hunters on the Ohio River was identified by the USAF as a balloon-borne magnetometer used for magnetic field research. The item was processed through the OSI and ATIC for analysis.
This document details the recovery and subsequent identification of an object found by two hunters along the Ohio River in Indiana on February 4, 1958. The object, described as a round device constructed of half plastic and half fiber, was turned over to the Office of Special Investigations (OSI) and subsequently analyzed by the Air Technical Intelligence Center (ATIC). The investigation concluded that the object was a magnetometer designed for the remote measurement of the Earth's horizontal magnetic field. It was determined that the device was likely transported to a high altitude via a balloon, from which it transmitted magnetic field strength data to a ground station via telemetry. The document includes a Project 10073 record card, a formal memorandum from Captain G. T. Gregory of the USAF (AFCIN-4E4) to the Commander of the 5th District OSI, and a handwritten note confirming the return of the item to the 5th District OSI on February 5, 1958, along with the evaluation.
The device is a magnetometer for remote measurement of the strength of the earth's magnetic field.

Official Assessment
The device is a magnetometer for remote measurement of the strength of the earth's magnetic field. It was probably carried to a high altitude by a balloon and then transmitted field strength measurements by telemetry to a ground station.
The object recovered by two hunters on the Ohio River was identified as a magnetometer, likely used for high-altitude atmospheric or magnetic research via balloon telemetry.
