Lights in the sky

Service industry night owl here. Anyone else see about 16 lights pass over in single file, led by two side by side at 0515? Just curious. Never seen a satellite passover like that in Houston, especially so bright. Saw a few satellites pass over at once during my 4 years in Alpine Texas, but never seen them pass in single file like that. I thought satellites all used different alt/long/lat? Any input is appreciated, cheers.
