ISS crossing the sky trailing behind Dragon CRS-17 spacecraft

This was a very bright pass of the ISS over Catalonia, and we were waiting for it to appear in

the sky (June 3, 2019). To our surprise, a smaller point of light appeared before at around 22:28 local time. The bright ISS was trailing behind !!! This point of light happened to be the unmanned spacecraft SpaceX Dragon CRS-17, that had been servicing the ISS and was then coming back to the Earth! It splashed down in the ocean just a couple of hours afterwards. It was like a wow!, inspiring view!
