Sighting was approx. 8-10 minutes in duration. Very large craf. Irregularly-shaped rectangle, appearing wider in aft, narrower forward with truncated front section. 4 large lights, 2 fore, 2 aft. Hung motionless above housing development. No discernible sound. Undercarriage was visible, appeared to be conduit in a complex array. Finally craft moved away from view at a slow rate of speed, heading SSW from our vantage point. My companion was noticeably upset having seen it.
To myself I said, "Thank you"
