Green UFO Streaks Across Alberta Night Sky

Satellite looking object turned into a flash of blueish green and then dissapearing!

I was at work (working nights) unloading one of our paint booths.  I was looking at the sky (which i do from time to time) when I noticed this circle object in the sky.

I thought it was a satellite moving across the sky so i kept my eye on it for about 10 seconds when literrally out of no where it took off so fast it turned into a flash of blueish green and then just dissapeared into the night sky.
