Darting light over Austin

Darting light over Austin
Time: 9:56Pm
Location: Austin, TX, North/Central. 

 The sky was clear of clouds. A solid bright ball of white light flew across the sky, at an even trajectory. It looked to cover a couple miles within half a second. It traveled from North to South. There was no sound. It didn't fade or go off into the horizon, it just disappeared. I would guess it was a couple thousand feet up, but I can't be sure. I had my pro camera on me but it happened so fast I didn't have time to even lift it up.

I texted my partner right after,  he's working overnight outside, East a couple of miles. I told him what I saw and he said he saw it as well. 

 I went inside, and my partner said he saw it happen 3 more times from 11:16 to 11:18PM. Twice in the same area/direction, and the last time in a different direction.

Edit: added object travel direction
