I was driving on the highway to scoudouc and just before the industrial park i saw this bright light. i thiught it was a street light and then realized there is none on the highway so then i thought it was a star. as i got closer i noticed the green light, it was above the trees i slowed down to about 90km/hr and noticed it was hovering, and spinning around and that it was an octagon like shape. as i passed it on the highway in my vehicle (12:20am & pitch black out) the lights disappesred.
