[redacted] was at the controls of the aircraft conducting VFR (Visual Flight Rules) at an altitude of 6,000 feet, when the first officer observed an unusual visibility which was moving rapidly on a north heading. [redacted] observed the object as it passed in front of the airliner. This object was sighted for approximately 12-15 seconds when the object passed directly in front of the airliner, the distance was not more than 1/2 mile and at an altitude of approximately 1,000 feet higher than the airliner. The object emitted 3 flashes per second. This light could be seen only when the object was approaching and after it had passed in front of the observer. The bottom side appeared to have a metallic oval or circular port which emitted small blue-green lights. The object was not revolving or spinning and considering the visibility, the distance from the object, the length of time the object was observed, it is the opinion of the observers that the object was not an aircraft or any known aerial vehicle.
