Green UFO with white rim seen in Colorado

Summary

A witness in Security, Colorado, observed a bright green object with a white rim moving at low altitude. The object, compared to a car's headlight, appeared among trees and disappeared within seconds. There were no photos or physical evidence, but the sighting was recorded under Project 10073. The description suggests an object with a luminous trail, raising questions as it couldn’t be identified as a conventional object.

The report includes details on location, time, and duration, though witness information is incomplete. The military considered it an optical illusion caused by a temperature inversion, but the sighting remains an unresolved mystery.
