AI-Generated Summary
A 1955 UFOB Index Card detailing a sighting of a long, silver object at Camp San Luis Obispo, California. The report concludes it was likely a balloon due to regional activity.
This document is a UFOB Index Card documenting a sighting that occurred at dusk on June 5, 1955, at Camp San Luis Obispo, California. The witness reported observing a single, long, silver object for a duration of four to five minutes. The object was described as being the size of a pea held at arm's length, and its movement was characterized as circling and ascending. The report explicitly notes that no photographs were taken and no radar contact was made. The evaluating officer linked this incident to a separate sighting in San Margareta, California, suggesting that the observers in both instances likely witnessed the same phenomenon. Due to the reported presence of significant balloon activity in the region, the official conclusion recorded on the card is that it is highly possible the object was a balloon, though the card also bears the notation 'Insufficient Data for Evaluation'.
With much balloon activity in this area it is highly possible that the UFOB was a balloon.
