Sorry. It was Saturday night! My brother and I were standing on the beach at a small lake near my house in Benzie County, MI at about 10:30 PM on September 28th. We were facing west and witness four lights that looked like stars to the northwest begin moving in four different directions away from each other (i.e. spreading out) at a slow and steady pace. They eventually gradually faded out from view. Over the next 30-40 minutes these lights would fade in and out of view and travel in different directions, sometimes in pairs or groups of up to four, or sometimes just one. Occasionally there would be two or three traveling toward the north and one traveling toward the south. They would also travel up, down, and diagonal at times. They always traveled at a consistent and relatively slow rate, and they would eventually fade out of view after a minute or two, and then reappear somewhere else in the sky, but in the same small area to the northwest just above the tree line. There was no sound, and they never changed colors or blinked. It was impossible to guess the distance they were away, although I will say that it seemed far. Northwest of this location is all farmland and national forest, and then Lake Michigan. If I had to guess I would say these were over Lake Michigan. This continued for at least half an hour, with the lights fading in and out of view and moving in various directions, always at the same speed. Eventually they faded out and didn't return, and we left the beach. My brother had his fancy camera and got pictures and video, which I will upload. Some of the photos are timelapses which show the trails as the lights moved, including abrupt changes in direction.
