They are no longer visible to the naked eye. The satellites are initially inserted at ~half their final orbit. They then boot up, deploy their solar panels horizontally to reduce drag, and then fire up their engines for the boost to their final orbit. This takes about a month or so. Once there, they rotate their panels to point away from the earth, which greatly reduces their apparent brightness.
