My wife, and family were sitting at the bonfire at our cottage. We observed a bright orange/yellow/red light approaching us from the south west. As object came over the top of us, it was pulsating and we noticed a round disc shape object about 500 -1000 feet in the sky. There were dark metallic lines on its under side. Object was moving approximately 70-80 mph rotating in a slow clockwise manner with no sound. It was about 200 ft in dia.((NUFORC Note: Correct date may be Auguts 15, but we are not certain, yet. PD))
