UFO Identified as Capella in Colorado Springs

Summary

A bright and pulsating object was observed for two hours in Colorado Springs, Colorado, in October 1956. Civilian and military witnesses described it as a red and green star-like object that didn't move but pulsed gently. It was seen at different elevations and azimuths in the sky and remained visible even after the observers went to sleep. The sighting was made with the naked eye and binoculars, increasing the credibility of the report.

The investigation concluded that the phenomenon was astronomical, specifically the star Capella. The data supported this explanation: the duration, apparent movement, and size matched a star viewed through three temperature inversions. This created an optical illusion making Capella appear larger and brighter than usual. The case was quickly and clearly resolved without further investigation.
