What I thought was space station overhead wobbled and accelerated straight into space.

I was at work taking some trash out to our dumpster.  It sits in the back lot of our shop.  After throwing my trash in the dumpster I looked up in the sky because of how clear it was outside.  
Almost straight above me, I saw a bright light moving across the sky.  I thought how cool, must be international space lab.  One of my co-workers was out painting and I called him on our work radios and told him took look up to the sky.  
At that point this object had traveled about an arm’s length across the sky.  All of a sudden this light started to wobble.   Then the light got smaller and smaller and then totally out of sight in a matter of a couple seconds.  I am thinking that when I saw it wobble it started accelerating into space.  
Never seen anything like it.  I hope someone else seen it because it was amazing.
