Project 10073 Record Card and Related Reports — Duluth, Minnesota, June 1961

This document consists of a Project 10073 record card and associated teletype reports regarding a UFO sighting that occurred on June 1, 1961, near Duluth, Minnesota. The primary report details an observation made by a witness at 0555Z. The witness, identified as a 32-year-old male associated with the Army Reserve Center, reported seeing a round, baseball-sized object that was bright blue in color. The object featured a yellow or red 'sparky' tail measuring eight to ten feet in length. The witness observed the object for approximately 15 seconds as it traveled in a straight path, descending to the west and losing altitude. The weather conditions at the time were described as damp and misty, with lightning reported to the northwest. The official evaluation, signed by Captain William R. Williamson of the Intelligence Division, noted that while the duration of the sighting was longer than typical for a meteor, the characteristics were consistent with a fireball. Consequently, the report was officially categorized as 'probably fireball.' The document also includes a summary table of sightings from June 1-15, 1961, which lists various reports from across the United States, including evaluations such as 'insufficient data,' 'satellite,' 'aircraft,' and 'astronomical' (Venus, Altair, Bootes). This summary provides context for the administrative handling of UAP reports during this period, showing how individual sightings were processed and categorized by the Air Technical Intelligence Center (ATIC) under the guidelines of Air Force Regulation 200-2.
