I was sitting in parking lot facing west/ northwest. Saw this bright green ball in western sky going from left to right- south to north -and heading downward. I was at first afraid a plane was crashing - our airport ( xna) is in the same area ( west of Rogers ar) of the green fireball The Ball was glowing bright in center but was overall green and had a tail. The ball disappeared behind a low cloud. I immediately took a pic of the evening skyincluding the cloud. The green fireball did not emerge from the cloud. I did not see any explosion. In same split second as I saw it I also wondered if a plane was crashing I also thought it was faster than a plane and a plane would not look green. That is all. It was very quick 2seconds? Maybe 3 seconds? The sky was not completely dark. Clouds clearly defined . It was beautiful
