Yellow-green UFO in Ohio disappears mysteriously

Summary

A 1960 report describes a spherical UFO seen in Christiansburg, Ohio. The object, yellow-green in color and the size of the moon, appeared as vapor and moved in circles. A dog barked at the object, reacting to the phenomenon. The witness observed it for 10 minutes, but it disappeared for a minute. Despite the detailed description, the data is considered insufficient for a conclusive evaluation. The lack of photos or radar tracking complicates identification.
