Bright green flash going up

There was a thunderstorm or heat lightening over the lake east of me. No sound so it must have been heat lightening and it became more rapid so I filmed it. I saw a blip in the corner so I stopped and reviewed it and saw this. And it was fast. Slowing it down there's a tail to it. I star watch all the time and the closest thing I can compare it to was a comet or something same color in Madison, WI I saw the night before my brother's graduation but to my knowledge comets or meteors don't go up....
