What flew over Trois-Rivieres, Quebec at 9:20 PM on 16 March 2013 that was reported to the MUFON database?

Me and my wife during a walk with our three dogs stopped in the little park at the end of the street. I observed in this evening clear sky Jupiter next to the moon. I'm an amateur of astromical observation so I always head up during these walks. Suddenly in right of the moon, a huge UFO ( bullet shape) in high stratosphere (entering from space ?) to follow the earth curve with incredible speed. It was not a meteor; I know the difference : no tracing or fire) ; only a clear shape, no noise.

It from east go to west during 3-4 secondes and desappear in the night. It was near big than the moon. It was glow white colour. I was very impressed by this so fast and big object. i was the only witness , my wife looked the dogs.
