January-December 1959 Sightings

This document is a comprehensive monthly log of unidentified aerial phenomena sightings reported during the calendar year 1959. Each page corresponds to a specific month, from January through December. The entries are structured in a table format, detailing the date of the sighting, the location, the type of observer (e.g., civilian, military, multi-witness, or airline crew), and an official evaluation of the event. The evaluations cover a wide spectrum of explanations, including astronomical phenomena such as meteors, planets (Venus, Mars), and stars (Spica, Fomalhaut, Betelgeux, Altair, Capella, Regulus, Sirius); conventional aircraft; balloons; and various other causes like reflections, missiles, missile debris, flares, and psychological factors. A significant number of entries are marked as 'Insufficient Data' or 'Unidentified'. Additionally, each month includes a section for 'Additional Reported Sightings (Not Cases)', which lists reports sourced from news clippings, letters, or science news summaries that were not formally investigated as cases. The document also notes that certain files were kept in separate folders, indicating a larger administrative system for managing these reports. The log serves as a historical record of the volume and nature of UAP reporting during 1959, reflecting the military and civilian interest in these events.
