Slow Moving Light West of WashburnOn 1/25/2014 at approx. 2330 hours I observed a light in western sky. It was at a very high altitude. The light was brighter than any stars in the area and it moved slowly. It also would come to a complete stop and hover. When it was moving, a bright light would appear on to extend from the light. It would move in the opposite direction from the side of the light extended out from. I suspect I was observing some sort of thruster being utilized when I observed this. However, I was not close enough to make that determination.The light came to a stop and hovered for about 5 minutes. It then rapidly began gaining altitude until it was no longer visible. I videotaped a few minutes of the phenomena however the video is of poor quality. The total time I observed it was approx. 10 minutes and light did not return while I was out in the area once it gained altitude and was out of sight.
