Our exact location at the time of the sighting was, 39.392370, -92.233883. I was staying the weekend at a friend's home. We were outside looking to the north. There was enough of a moon to beable to see the cloud bank. We noticed that there was a frosty green intermitantly blinking light that was moving south under the cloud bank. The only way to determine it's movent was compareing it's location from one blink to the other. The blinks had absolutely no patteren to them, they were completely random. Once the object came to the edge of the cloud bank it then moved up and then proceeded to go back north over the cloud bank untill it was out of view. At no time did we hear any engie noise. The object had only the one light, no normal FAA lighting, and agian the one light strobed with no set intervals.
