I don't know the actual location I saw it, I was driving north on 495 somewhere between exit 37 and exit 40. I saw it to the left of me over trees. It was green and had a trail of dots so I thought it was a firework. It lit up the sky and clouds. It had a cracking sound like a firework or thunder. I was driving approximately 75 miles per hour but the light still went from directly to my left (9 o'clock) to about 10 o'clock.
