Unexpected patterns in historical astronomical observations

Fascinating. "The second paper, published in Publications of the Astronomical Society of the Pacific (PASP), specifically looks for signs of possible extraterrestrial artifacts in orbit around Earth, before the first human satellite launch in 1957. The researchers looked, among other things, for instances where multiple flashes of light were along a line or in a narrow band—something that indicates reflections from flat, reflective objects in motion. Two interesting examples were identified, one of which occurred on July 27, 1952, the same night as the notable sightings of UAP in Washington, D.C."
