R. S. Dunbar, M. A. Barucci, and E. F. Helin (Palomar Mountain
   Observatory). Measured by Dunbar, assisted by Helin and Barucci,
   with manually-operated PDS scanning microdensitometer.  Observations
   made with 1.22-m Schmidt, except that on Aug. 30, which
   was obtained with the 0.46-m Schmidt.  B ~ 15 on Sept. 1 UT.
C. Kowal (Palomar).  1.22-m Schmidt; measured by Dunbar et al.
D. Tholen, D. Cruikshank, and W. Hartmann (Infrared Telescope
   Facility, Mauna Kea).  Positions read from S/K encoders.

     Orbital elements are from 8 observations, Aug. 30 to Sept. 4:
