A Civilian Astronomer's Guide to UAP Research

Brief

The paper contends that the renaming of 'flying saucer' to 'UAP' inadvertently collapsed a phenomenon with defined observational signatures into a junk-drawer category, undermining falsifiable inquiry. Drawing on GEIPAN's 3,037-case database (3.3% firmly unresolved as of 4 January 2024), declassified Project Moonwatch records from the 1950s–60s, and the VASCO project's pre-Sputnik photographic-plate transients, the authors map how stigma has suppressed data quality, including the outright destruction of Moonwatch reports at reporting stations. As a corrective, they advocate calibrated multi-sensor campaigns modeled on standard astrophysical transient methodology, and introduce a speculative toy model of neuro-interface ET probes to derive predictable probe signatures and guide experimental design.

Key points

• GEIPAN's 3,037-case database shows 3.3% firmly unidentified and 32.4% unresolved due to insufficient data, a hard lower bound, not a true prevalence estimate.p.4
• Co-author Krisciunas logged at least 1,029 nights of open-sky professional observation; four events (0.4%) qualified as anomalous, and one, a grey elliptical object witnessed at a school in May 1964 near O'Hare, has no accepted explanation.p.8
• Project Moonwatch (1956, Smithsonian Astrophysical Observatory) created a global citizen-science optical fence to track Sputnik; its UAP sub-sample is a lower bound because observers destroyed reports before submission to avoid stigma.p.12
• The San Antonio 1959 Moonwatch event: two experienced observers with co-boresighted scopes simultaneously tracked two objects on a near-collision course that veered away, corroborated by a third observer at the zenith, the longest account in the Hynek File at 17 pages.p.13
• VASCO project reported groups of transients appearing and vanishing within half an hour on pre-Sputnik photographic plates; the two most compelling cases coincide timewise with the Washington 1952 UFO flap.p.5
• Carl Sagan estimated in 1963 that Earth may have been visited 10^4 times by civilizations traveling at near-light speeds, cited here to motivate near-Earth artifact searches that many SETI conferences explicitly exclude from their programs.p.3
• The paper frames the UAP label as a liability: it turned a phenomenon with specific signatures into a category defined only by what it is not, making hypothesis testing nearly impossible without narrower sub-questions.p.2
• A toy model of neuro-interface extraterrestrial probes is introduced as a thought experiment to predict probe signatures and calibrate detection campaigns, not as a physical assertion.p.6

Verbatim

• “As of 4 January 2024, the French association GEIPAN estimated that out of 3037 reported cases, 3.3% remain Unidentified Anomalous Phenomena, and another 32.4% stay unidentified mainly due to a lack of accompanying data [22].”

Most interesting

• Krisciunas's most dramatic 1969 'UAP', a glowing nebular object in the Great Square of Pegasus, resolved three months later as 26.6 pounds of water dumped overboard by Apollo 12 astronauts from 110,000 miles away, confirming the importance of delayed cross-referencing.
• Carl Sagan, who estimated 10,000 ET visits to Earth in 1963, later reversed position and became a UAP skeptic, a trajectory the authors invoke to illustrate how institutional pressure shapes scientific opinion independently of evidence.
• Charles Messier observed multiple large, dark objects moving in what he described as 'organized' formation during a lunar eclipse on 17 June 1777; no conventional explanation is on record.
• Some SETI conferences explicitly exclude near-Earth artifact searches and UAP from their programs, a structural asymmetry the authors flag against the backdrop of mainstream willingness to entertain Dyson sphere candidates at interstellar distances.
• Krisciunas identified a pulsating red object at zenith angle 90° on Mauna Kea in 1994 as Venus only after consulting the Astronomical Almanac post-observation, illustrating that even professional observers can be systematically misled by extreme atmospheric refraction.
• The 1959 San Antonio Moonwatch report, marked 'for J. A. Hynek only', included original handwritten correspondence, typed transcriptions, and three key drawings, and was not shared between the two primary observers until one or two days after the event.
