Mueller reports that J. Phinney discovered a fast-moving asteroidal object on an exposure by P. Moniot and C. Brewer on Feb.27 with the Oschin 1.2-m Schmidt telescope in the course of Palomar Sky Survey II. She has measured the following positions from that and a follow-up exposure on Feb. 28: 1989 UT R.A.

Marsden, Center for Astrophysics, are necessarily very uncertain, but the ephemeris may help observers locate the object: T = 1989 Feb. 8.32 ET Peri. = 144.56 e = 0.6429 Node = 348.02 1950.0 q = 1.0013 AU Incl. = 7.58 a = 2.8036 AU n = 0.20995 P = 4.69 years 1989 ET R.A.
