four linear orange lights horizontally crossing the skyline by night while rotatingI very clearly saw something in the shape of four linear, closely equidistant, dim orange lights with no apparent material link between them. It horizontally crossed my clear night skyline east to west, while partially rotating clock and counterclockwise as if on an axis. It than stood still for a few seconds and dimmed away rapidly.It was soundless, trail-less, fast and very smooth. The sighting didn't exceed 20 second in all.I was standing on the house first floor terrace facing the sea. I could not evaluate speed or altitude. It could equally have been close or distant.
