It is structured as a series of monthly tables, detailing the date, location, observer type, and official evaluation for each entry. The reports span a wide geographic range, including numerous locations across the United States, as well as international sightings in countries such as Japan, France, Germany, Canada, and Brazil. The observers are categorized broadly, including military personnel, civilian pilots, radar operators, and general civilians.
