C. S. Shoemaker, E. M. Shoemaker, and H. E. Holt (Palomar).
C.-Y. Shao and R. E. McCrosky (Oak Ridge).  1.5-m reflector.
  Images slightly trailed; comet strongly condensed with coma.
A. Maury (Observatoire de la Cote d'Azur, Caussols).  0.9-m Schmidt
  telescope, 103a-O plate, 25-min exposure.  Faint 30" tail between
  p.a. about 217 deg and 290 deg.  Communicated by C. Pollas.
T. Niijima and K. Kanai (Ojima).  0.30-m f/5.8 reflector.
H. Shimoda and K. Kanai (Kamihoriguchi).  0.30-m f/3.8 reflector.
M. Koishikawa (Sendai Observatory).

     The following preliminary parabolic orbital elements are from the
above observations, but it seems likely that this is a short-period comet.

     T = 1988 Sept. 5.31 ET           Peri. = 321.34
                                      Node  = 112.81    1950.0
     q = 1.5584 AU                    Incl. =  20.90
