G. Schwartz and R. E. McCrosky (Oak Ridge Observatory).  Beginnings
   and ends of trails (two 3-min exposures) obtained with the 0.41-
   m astrograph.  Measurer:  McCrosky.
E. and C. Shoemaker (Palomar Observatory).  Films taken with 0.46-m
   Schmidt telescope.

     The following orbital elements by C. M. Bardwell, Center for
Astrophysics, indicate that this is probably an Apollo-type object.
