Calm warm, bright night. My father and best friend and I were on our way to McDonalds down a back country road. He was yelling and pulled over and yelled for us to look at the country house. It was the only house there for miles. There was a disco ball like craft "sphere" the size of two large cars/busses together with random lights shining all around it, the gleam from the lights blended into the night sky all around the sphere. There was a humming sound and the craft was hovering still above the tree line which was right of the full moon. The sphere was shining a blue/green single beam of light across and back across the top story three popped out bedroom windows, then the beam of light went out, then the object swayed to the left towards the moon then was gone from our sight.
