1988 VP4
     C. S. Shoemaker has discovered another fast-moving asteroidal
object on films taken with the 0.46-m Palomar Schmidt telescope by
E. M. Shoemaker, H. E. Holt and herself.  The following measurements
are by C. S. Shoemaker and T. Rodriquez:

           6.26875   23 54 23.14   +26 52 08.2

     Orbital elements by C. M. Bardwell, Center for Astrophysics, show
that the object is of Apollo type.  The object is intrinsically rather
bright and will be well placed for observation in the southern hemisphere
next March and April, with a passage some 0.23 AU from the earth.
