Above my yard about 200 feet there hovering and no noise or movement was a round craft with a dome top. White lights no blinking No noise or movement Above the lights were several large windows with occupants behind them with some movement. I waved to them and smiled at them to show that I also was friendly. I ran into my house to get my binoculars to see if they waved back. I was gone less then 30 seconds. When I came back the craft was gone. No noise no lights any where in the skies. Just gone. I feel very strongly that they were friendly sightseers. It was a wonderful experience. To have seen this .
