Stephen Bruehl and Beatriz Villarroel examine pre-Sputnik Palomar Observatory Sky Survey transients against nuclear-test dates and UFOCAT reports across 2,718 days. They report a 45% higher likelihood of transients within a three-day nuclear-test window and an 8.5% increase in modeled transient counts per additional UAP report. The paper treats proposed origins as hypotheses, disclaims identification and causality, and discusses automated detection, unvalidated witness reports, geographic mismatch, and possible multiple causes.
