Incident #132 Sighting Report — Oslo, Norway, 12 December 1947

This document details the investigation of a luminous object sighting reported by a 16-year-old female civilian in Oslo, Norway, on the night of 12 December 1947. The witness described an intense white object with a greenish-yellow tail that traveled in an arc from SSW to NNW. The observation lasted approximately two to three seconds. The witness noted that the object was not as fast as a typical meteor and that there was no associated sound. The sky was reported as clear and star-lit at the time of the sighting. The report was initially processed by the Intelligence Department, with C. A. Griffith requesting that the witness be interrogated and that the University of Oslo provide expert commentary. However, the University Observatory had no record of the specific incident, although an employee noted an unusual number of falling stars on 13 December 1947. By September 1948, the investigation reached a conclusion. HQ USAF advised that no further useful purpose would be served by questioning the witness eight months after the event. The official evaluation categorized the object as a fireball, noting a high probability that this assessment was correct. The document includes various administrative forms, including a checklist for unidentified flying objects and an incident index from the Project Grudge report, which lists incident #132 under the 'Astronomical' category with high probability.
