Schematic representation of planned 12000 Starlink satellites which will be visible during a summer night, at 32° latitude (north is up).
Only illuminated satellites are shown. This is a "schematic" simulation of all visible passes - most of the satellites won't be visible to a naked eye (however they will be visible through a telescope or in long exposure photos). Here can be found a real time video of a "naked eye view" of a small portion of the sky: https://www.youtube.com/watch?time_continue=124&v=0BfB7TQF4cs&feature=emb_title
Note that during summer there will be significantly more visible satellites - they will be illuminated during the entire night and not only at sunrise or sunset.
