Project 10073 Record Card — 18 August 1956, Colorado Springs, Colorado

This document is a Project 10073 record card detailing a civilian sighting of an unidentified object in Colorado Springs, Colorado, on 18 August 1956. The witness reported observing a single, round, bright white object that appeared to be the size of a silver dollar held at arm's length. The object exhibited a bouncing movement and its brightness varied during the four-minute observation period. The sighting occurred at approximately 90 degrees azimuth and 40 degrees elevation, and the object remained visible to the observer until they went to bed. The record notes that this sighting was identical to a previous report made by the same source on 14 August 1956, which was documented under reference number AISS-UFOB-287-56. Upon follow-up investigation, which included a telephone contact with the source, the object was officially identified as the planet Venus, with the visual phenomena attributed to the effects of a temperature inversion.
