Rectangular light fixed in the Northwestern sky for over 3 hours.

My wife and I were sitting outside giving out Halloween candy to the kids when I noticed a bright rectangular white light (with binoculars looked like two lights on top of a long bright light) to the NortWest. Wind blowing at ground level but rock steady. Maintained the same position for three hours before it became too cold and we went inside. Airplanes flying over and under. Clearly not an airplane or helicopter or consumer drone (no drone can hover for three hours). I am a retired police officer with an aviation background and hold an FAA Commercial Pilot certificate.
