I went outside to have a cigarette at approx 1:15 am. looked up in the sky and saw at first what appeared to be a single light moving at a pace similar to the space station. what caught my attention was that it was traveling e. to w. as i continued watching, i realized that there were 7 or 8 lights in total and they went from a tight grouping, to spread out, to switching places. as they passed just to the west of my location, they turned on a nw trajectory before resuming their westward path, disappearing below the tree line shortly after.
