I was taking groceries in from my car and saw the object and called my son downstairs to look at the object. My son thought it was a weather balloon, but it was hovering. The object was silver or lead colored. It had red lights on what appeared to be a dome, and white lights on the side. If was disk shaped, like a saucer. It was moving very slow from the north, it was hovering. And then it took a westerly turn and went behind trees and we lost sight of it. We also heard sirens behind the trees. So maybe we weren't the only people who noticed this unknown object. My son said that he could hear a beeping or humming sound coming from it as it moved. We were both shocked and confused about this.
