The object was round with no tail and no sparks. It was a vivid green. The color reminded me of a traffic green light or a fireworks fragment but there were no fireworks around. It was much too big to be a fireworks fragment. It seemed maybe half the size of a full moon. I was surprised by how slowly it moved compared to a typical meteor but the speed was much faster than a fireworks spark falling. I heard no sound from it. It appeared to be falling down to earth but with a slight but definite angle from right to left. We were facing North. It disappeared after only a second or two.
I wasn't sure whether it had actually vanished or had gone behind clouds. Also trees and houses would have blocked our view to the horizon had it reappeared.
