C. S. Shoemaker reports her discovery of a fast-moving asteroidal
object on films taken by E. M. Shoemaker, D. H. Levy, and herself
with the 0.46-m Schmidt telescope at Palomar, as follows:
1991 UT R.A. (1950) Decl. Mag.
Nov. 7.28750 0 52 06.08 +24 48 39.2 17.2

The following orbital elements by B. G. Marsden, Center for
Astrophysics, are necessarily very uncertain:
T = 1992 Mar. 16.554 ET Peri. = 224.862
e = 0.85655 Node = 320.390 1950.0
q = 0.27062 AU Incl. = 10.326
a = 1.88650 AU n = 0.380382 P = 2.59 years
