     Precise positions measured by C. Shoemaker from exposures by
E. Shoemaker and herself with the Palomar 0.46-m Schmidt telescope:

     1984 UT             R.A.   (1950.0)   Decl.       Mag.

     May  27.44930     17 58 12.20     +15 27 01.7     13.5

          30.36875     17 31 56.10     + 9 38 16.7

     The object appears to be of Apollo type.  The following orbital
elements are somewhat uncertain, but the ephemeris will
perhaps serve to locate the object:

           T = 1984 Apr. 4.91 ET
       Peri. = 337.69                    e =   0.8191
       Node  = 167.56   1950.0           a =   2.7912 AU
       Incl. =   4.92                    n =   0.21136
           q =   0.5048 AU               P =   4.66 years

     1984 ET     R.A. (1950.0) Decl.      p        r      Mag.
