UFO seen over San Francisco in 1955

Summary

In May 1955, a civilian in San Francisco observed a bright object in the western sky. The witness used binoculars to see a round object the size of a pinhead. The object remained stationary for a few minutes before disappearing rapidly. The observation lasted about five minutes. Although initially considered a balloon or aircraft, the data suggested an astronomical object.

Researchers believed the object could be Jupiter, as its position and brightness matched the planet. The direction of the object and the witness's description supported this theory. No photos or radar were used, so there were no physical proofs. Eventually, it was concluded that further investigation was unnecessary, as everything pointed to an astronomical explanation.
