Summary

In September 1963, a woman in Bloomington, Illinois, observed a round, white object for over 30 minutes. The initial report classified it as an astronomical phenomenon, though other possibilities were not ruled out. The observation was made without optical aid, adding to the mystery. The witness, a 20-year-old housewife deemed very reliable, saw the object moving from south to southwest before disappearing behind clouds.

Captain John G. Mullin concluded the object was Jupiter, whose movement and position matched astronomical data. Additionally, police confirmed the object pointed out was a very bright star. Despite the clear explanation, the report was carefully processed, reflecting the thoroughness with which sightings were handled at the time.
