They are launched into low orbits where they are often visible to the naked eye, as a train of 50 or more satellites following each other across the sky. It's quite a sight. Over a few weeks they raise their orbits to operational altitude. Once they reach it and orient themselves for operation they are much dimmer and can't be seen without magnification. So the vast majority of orbiting Starlink satellites are invisible to the naked eye.
