Transients on Palomar POSS-I Plates: A Possible Connection Between Cold War Nuclear Tests and UFO Sightings
To the point
Stephen Bruehl and Beatriz Villarroel report that brief luminous transients recorded on Palomar plates between 1949 and 1957 occur more frequently on days of atomic testing and near spikes in UFO reports, suggesting they may reflect secondary effects of nuclear explosions such as Cherenkov radiation and warrant further empirical study, though no direct causation is claimed.
