Outside next to riverbank talking with 2 other friends. Looked up into the night sky just to observe stars. Thought it was a shooting star for an instant. The object was bright and all white, non flashing, circular with absolutely no sound. The object was surrounded with a white glow like aura which was slightly dimmer then the center source of light. It flew in a straight path overhead at about roughly 300 feet. Really curious as to what this was. Reactions from the three of us were "what is that?" We compared it to a few airplanes higher than the object and it varied greatly to that of a typical plane. We lost sight of the object due to cloud coverage.
