* Orbital Elements

   The following improved orbital elements by Kenji Muraoka, are
  from 105 observations 1999 June  9 to 2000 Jan. 18, perturbations
  by 9 Planets, Moon and 5 minor planets were taken into account.
   The mean residual is +/- 0.54 arc seconds.

      Epoch  =  2000 Jan  = 2451560.5
          T  =  2000 Jan.  4.90822       +/- 0.00033 (m.e.) TT

       Node  =  140.16085                +/- 0.00045   (2000.0)
       Incl. =  166.09933                +/- 0.00008
          q  =    1.9889094              +/- 0.0000059 AU
