The pinkish orange lights dimmed out as the diamond shaped object moved overhead toward the east.I walked out of the house toward the west and I saw a pinkish orange light flickering (like an arc welder does when welding) across the width of the front of the object coming toward me. It was bright at first and dimmed to a dull red as the object approached , then it dimmed out as the diamond shaped object moved slowly overhead. It appeared to be a light grey or dull white with no lights at all about 40 percent of the size of a full moon. It continued to fly slowly and silently directly overhead toward the east-slightly southeast direction at a constant slow speed until it disappeared into the tree line. There were no clouds, no wind ,it was an absolutely clear sky.
