UFO seen in Chicago with illusory three moons

Summary

In May 1964, a witness in Chicago reported a sky phenomenon involving three crescent-shaped objects. The report details a brief observation, lasting only three seconds, with features like oscillating motion and greenish glow. The observer, an amateur astronomer, described an intense and memorable experience. Although initially considered an astronomical event, it was suggested it might be an after-image caused by the red light of his flashlight. The communication between the witness and experts like J. Allen Hynek reveals a careful analysis, considering factors like dark-adapted eyes and the precise location of the phenomenon. Despite doubts, the witness insisted it wasn't a conventional event.
