Fireball appears on the horizon, shoots object from it, splits into two, then disappears.We were sitting on the beach at night looking at the horizon. A bright fireball just appeared right above the horizon and then split into two equally bright circles and then disappeared completely after about five seconds. About two minutes later, it reappeared to the left of us and a lot closer than before. It appeared as one and just before it split into two again, something like a duller red spear shot off of the fireball and traveled a short distance to the right and angled towards the ground and then it disappeared. Then within seconds the fireball split into two and disappeared again.
