This rock needs to be watched carefully as the orbit uncertainty (now 8) will surely improve. Since this large rock is trailing behind us and only slightly above the ecliptic, the observations are only producing a very short, straight line. Not very good for orbit calculations. As it nears and catches up in late May, the orbit uncertainty will vastly improve. As it nears close approach (June 12), we should have much better, the ability to produce good ephemerides.
