I was sitting on my second floor balcony with my back to the house, facing southwest. It was twilight, just the glow of the sunset, clear sky, the sky still blue not dark yet. I was having a snack, tipped my head back for a bite and saw an orb the size of a baseball, maybe softball size that was white surrounding it and the center of it a green color that trailed slightly behind it and then the white trail line behind it all. It came directly behind me from over the house, so I didn't see it coming, that would be from the northeast, seem flat on top of me, parallel to the earth surface, honestly seemed like it was just above the treetops. I'm up high in the neighbor hood and have a good view but I didn't see it continue into the horizon, it was so fast it was just gone. It almost looked like someone shot a firework level. Never saw anything like this!
