Orange fireball split into 4 equal sized spheres then disappeared.A large yellowish orange fireball appeared in the Eastern sky about treetop high. It was silent and remained in the same spot. I watched it for about 45 seconds as it split from one large fireball into two smaller ones and then into 4 parallel spheres of equal size. Then it disappeared instantly without a sound. This is the 2nd one we've seen. The other was last year but it didn't split.
