It was an emerald green ball with a short tail. The leading edge of the ball had a yellow glow. It's size caught my attention. It wasn't huge but it certainly wasn't like the thin lines that I normally see in the August meteor shows. It was much earlier in the night than I expected and much lower on the horizon. I have no astronomy experience but I stay up to watch the August meteor showers every year. I have never seen something like this before.
