2006 OZ2

  MPC indendified that a fairly dim object, found by Q.-z. Ye and H.-C. Lin on July 19 and successfully follow-up by Q.-z. Ye and C. S. Lin on July 20, is the same object and give it a new designation 2006 OZ2. The object was re-observed on July 28 by T.-C. Yang and Q.-z. Ye, confirmed it is a member of Jovian Trojan L4 (Greek group). The very first orbit elements were published on MPEC 2006-O65 as follow:

From 9 observations 2006 July 19-28.  E-assumed.

  Though the object is still E-assumed, the orbit would not change very much. With H=14.0(diameter about 9km), the object is the largest found by LUSS up to date.
