UFO/UAP Sightings Reports — January to December 1968

This document is a comprehensive, chronological compilation of reported Unidentified Aerial Phenomena (UAP) sightings occurring throughout the calendar year 1968. The report is structured into bi-weekly or monthly segments, detailing the date, location, and official evaluation for each reported incident. The sightings span a wide geographic range, primarily within the United States, but also including international locations such as Canada, Australia, and the Canal Zone. Each entry is assigned a case number, and the evaluations provided by the investigating authorities categorize the phenomena into various groups. Common explanations include balloons, aircraft, astronomical bodies (such as Jupiter, Sirius, Arcturus, Altair, Venus, and various stars/planets), and satellite activity (including satellite decay and specific satellites like Echo I and Echo II). A significant portion of the reports are categorized as 'Insufficient Data' or 'Other (Unreliable Report)'. Some entries note specific conditions, such as 'Confusing Data', 'Other (Conflicting Data)', or 'Other (Ground Lights)'. A small number of cases are explicitly labeled as 'Unidentified'. The document also includes a section for 'Additional Reported Sightings (Not Cases)', which lists reports that were not formally investigated as cases, often citing sources such as news clippings, letters, or data sheets from organizations like NICAP. The report provides a systematic overview of the volume and nature of UAP reporting during 1968, reflecting the investigative process of the time in attempting to identify and categorize these aerial observations.
