We were driving southward direction on the road indicated and saw the fire ball moving in a southward direction in a downward motion. We didn't hear any sound. We only saw the greenish (my husband says, blueish/greenish) all. It seemed rather large and move very fast. It happened in just a couple seconds then was out of sight. I've never seen anything so close to the ground. Usually see shooting stars but are always much higher in the sky and seem to look smaller(maybe because of distance). I was amazed!
