Aligned, multiple-transient events in the First Palomar Sky Survey
Four POSS I images showing a transient that appeared in a red-band exposure on July 19, 1952 (upper left) but vanished within 10 minutes and never returned. Bottom Line: Researchers analyzing 1950s astronomical photographs—taken before any satellites existed—found unusual patterns of aligned flashing lights and a striking shortage of these flashes in Earth's shadow. The patterns are statistically significant but can't definitively rule out camera artifacts. Key Facts: Dataset : Palomar Observatory sky photos from 1949-1957, before Sputnik Method : Searched for multiple bright spots aligned in straight lines within single photographs Primary Finding : Several candidate alignments with strong but not conclusive statistical patterns Shadow Pattern : Highly significant shortage of flashes appearing in Earth's shadow at satellite orbit height Historical Correlations : Flashes 45% more likely near dates of nuclear weapons tests; also correlated with UFO report dates from tha...
