So it was on July 19, 1952. At around 8:52 p.m., the photographic plate recorded the light of three stars of approximately 15 stellar magnitude. And on the second one, taken at 9.45 p.m., they were not found. They did not appear in any other photos taken in subsequent years

幾個可能 
1.  一個物體放被亮
 The first of them was that they were not three objects, but one. For example, a star that unexpectedly increased its brightness due to a rapid radio burst of a magnetar.


2.  小行星
 these objects were asteroids from the Oort Cloud that were “highlighted” by some event.

3. 核爆 產生
the third theory was that the “three stars” were not space objects at all
where nuclear weapons tests were conducted. Radioactive dust could easily get on the plate and create a false image.
