Description: My son and I were at Niagara Falls on the American side, on the observation deck. He was laying on a bench looking up. I was looking at the American falls. He kept yelling: “mom, mom, what’s that?” And he was pointing up. I looked up and at first only saw a low large cloud, but I could see something above it some lights. Then as the casino spot light passed around and it the light bounced off it. You could see that it was solid, noiseless and huge maybe 300 feet across it. It stayed from 8 PM to 10 PM and then disappeared. Note to Commenters: If you are reporting a sighting, be sure to include the location (city, state, country), date and time of your sighting.
