This is a 2023 draft research paper by Richard M. Medina and Simon Brewer of the University of Utah and Sean M. Kirkpatrick of the Department of Defense, prepared for journal submission and released in full by AARO in 2025. It analyzes 98,724 NUFORC public sighting reports from 2001 to 2020 by county with a Bayesian model. It finds that more light pollution and tree canopy mean fewer sightings, while more air traffic and military area mean more. Cloud cover showed no relationship.

Figure 2 NUFORC Reported Sighting Spatial Distribution for the Conterminous U.S. from
2001-2020
In the spatial sciences, data like these are typically referred to as Volunteered
Geographical Information (VGI). VGI are geographic information that are volunteered either
knowingly or unknowingly by individuals, typically with the assistance of location enabled
digital tools (Goodchild, 2007), and the issues connected to the use of these datasets has been
extensively discussed. Those vulnerabilities are present here, along with others given the nature
of this dataset. Like with other crowdsourced data, there is little hope for assurance of quality for
VGI (Goodchild and Li, 2012). This problem is furthered in this dataset where some may be
trying to actively disinform. It is clear that these data cannot be verified, and even if interviews
with each person were possible, there would be issues determining truth and accuracy, especially
given the historical attributes of the reports. However, NUFORC does include disclaimers on
their reporting page to help remove false reports. First, they provide information including
descriptions, images, and video of Starlink Satellites, which can look unidentified to those that
have not seen them before. Second, they provide a description of Venus, which was discussed
previously as a potential for unidentified sightings. Third, NUFORC discusses hoax and joke
reports, which are said to be ignored and discarded (NUFORC, 2023c). Given the size and
structure of the data, it is not clear that all hoaxes can be identified, but at least NUFORC is
paying attention to hoax cases. Nor can we differentiate those sightings that have obvious and/or
logical explanations, but we note that these still represent an ‘unidentified’ sighting. Still, this isPage determined to be Unclassified
