UFO seen reflecting lights in Washington DC

Summary

In June 1963, a witness in Washington DC observed an oval object with a greenish glow moving through clouds. The object appeared and faded depending on the sky conditions, moving back and forth from south to southwest. A pinkish glow surrounded it, and it remained visible for over an hour. The investigation concluded it was searchlight activity reflecting on mist and clouds, though the object's description didn't easily fit conventional explanations.
