Bright white light traveling rapidly across the sky, then disappeared, in Prince Edward Island, CanadaIt was a clear night with a phenomenal amount of stars. We watched a bright light traveling ESE from WNW at a rapid speed. It was the brightest light in the sky. There were no green or red flashing lights visible at any time. It took approximately 2 minutes to travel across the sky.We had 4 witnesses.It got smaller and smaller as we watched and finally disappeared.One witnesses is a mech/elec engineer with several patents. He estimated the object to be flying at approximately 25,000 feet. Color temperature of the light was cold. It was way under the speed of a shooting star, way over the speed of an aircraft.Lat 46.1667*N Long 62.6500*W
