U.S. Air Force Technical Information Sheet — Sturgeon Bay, Wisconsin, February 1953

On February 20, 1953, a 15-year-old female witness in Sturgeon Bay, Wisconsin, observed an unidentified aerial phenomenon for approximately one hour and ten minutes. The witness described the object as a small, yellow, lemon-shaped entity that resembled a candle flame. According to the report, the object remained stationary throughout the observation period, although it reportedly 'went out' two or three times before reappearing. The witness noted that there was no sound associated with the object. The observation occurred in a field covered with snow, and the witness returned the following day to inspect the site for physical evidence, such as footprints or signs of fire, but found nothing. The weather conditions at the time were described as cold with a strong wind and no trace of daylight. The witness expressed that she had no personal opinion on the nature of the object, though she admitted to being frightened after hearing stories about 'flying saucers' and the planet Venus. The official U.S. Air Force conclusion for this incident was that the object was likely an astronomical phenomenon, specifically the planets Venus and Mars, which were visible in the western sky at the time of the observation.
