Unidentified flying object south of AustinWe saw and watched a single object in the sky, which was south of Austin. It would change colors from a bright blue to an orangish and it would move up and down erratically. As it was moving up and down, it was moving also from East to West, in a zig-zag motion. We could not determine the shape, but only the bright lights which were blinking quickly and changing colors. As it moved further west, we lost site of it, however, it continued to move westward.
