Suspected astronomy in Sioux City Iowa

Summary

In March 1956, an observer in Sioux City, Iowa, reported a round object the size of an orange that appeared like a star and moved westward. The phenomenon lasted only a few seconds, and although no photos were taken, it was considered a ground-based visual observation. The object's description and trajectory drew attention, but there were no additional data to confirm whether it was a meteor, a balloon, or something else. The official conclusion pointed to an astronomical explanation, though the brief and mysterious nature of the sighting left room for speculation.
