At first I thought it was fireworks, but realized that it was odd that it was coming down rather than going up. Looked like a big, bright green sparkler.

Remarks
I only heard one boom and it seemed to be a couple minutes after I saw the fireball. Sounded much like an airplane breaking the sound barrier. It seemed to be far behind where I was standing rather than the direction I saw the fireball.
