When I was watching the perseid now, a row of bright shining objects came from south, crossed Perseus and headed north.
It was clear for me that these objects came outside our atmosphere. I had not rigged the phonecamera for the dark, therefore I share an illustration.
@halewanheda It looks to me as they have an altitude quite higher than ISS and the speed are also faster than ISS. The earths gravity holds them there so we'll see at night. Never seen anything like it myself.
