CONTEXT: Nine Transient Starlike Objects in a 1950 Palomar Sky Survey Plate

Here is the research paper from Nature Scientific Reports, “Exploring nine simultaneously occurring transients on April 12th 1950”, describing nine starlike objects recorded on Palomar Observatory Sky Survey red plate XE 325, a half-hour exposure. This is, of course, seven years before the launch of Sputnik, and the images show no trails as would be produced by aircraft or Earth satellites, even in geosynchronous orbits, although transient flares from objects in high orbits are a possibility. The objects do not appear on earlier plates of this region and have never been seen since.

This is probably the closest thing to a UFO report ever published in a Nature journal.
