Big bright white light with pulsating red-circle light in center crosses horizon going from West to East.Sunday, Sept 11, 2016, 12:05 AM, Ottawa, Ontario, Latitude: 45°18'N. Longitude: 75°39'W. I woke up about midnight and went over to the bedroom window to adjust the venetian blind. I saw a bright light in the sky, much bigger than any star, about 10 degrees above the horizon. It seemed to be somewhat horizontally oblong in shape and not moving at first. Then it started moving, slowly at first, then picking up speed, going from West to East. Finally, it crossed the visible horizon and going at quite a clip, it seemed to be about one or two miles away. It wasn't going much faster than a small airplane not too far away. But the light was much bigger that would be attached to any airplane which usually has more than one light. The window was open but there was no sound. There are small airplanes and helicopters that fly over all the time but I have no trouble hearing them even when the window is closed. It was not possible to discern any definite outline since the object was shinning so bright. The main oblong light was white with a slight bluish tint. There was also and just a tiny bit smaller, and more perfectly round, red light, that pulsed on and off about once every second, in the middle of the object. There have been previous sightings by myself in this area of the sky.
