That's where they'll be when they are still in the sunlight but the ground is in the dark. Earlier in the orbit the ground is sunlit too so you can't see them and later in the orbit they are in the Earth's shadow so you can't see them.
I just checked http://www.satflare.com/track.asp?q=StarLinkLaunch#LIST and it looks like it will be visible over a large section of the western US right now.
They are in orbit, not stationary over Utah.
