I was sitting on a chair in my living room when I saw the fireball out the window. It was large and bright and moving slower than I would've predicted a fireball to move. Much slower than meteors in a meteor shower (as they streak across the sky) and much closer to the ground. I haven't seen a fireball before, it was really interesting to observe. It was very green in color and I wonder if meteorites might have made it to the ground. It was generally headed from North to South.

Remarks
I saw the fireball through gaps in the row of arborvitae between my yard and the neighbor's, the fireball got larger between gaps. It appeared that there were a few bright spots in close proximity through the last gap that I could see it.
