3089 Oujianquan is an main belt asteroid with an estimated diameter of about 10 km. It was discovered on December 3, 1981 by observers at the Purple Mountain Observatory near Nanking. The semi-major axis is 2.95 AU, the eccentricity is 0.182 and the inclination is 16.68 degrees.
Observations of this asteroid were made on six nights during June 2004. However each night’s run was less than 4 hours duration. As a result each night covered only a portion of the lightcurve. The accompanying lightcurve is a good fit to the data, however, in view of the limited duration of each observing run, it still has some uncertainty associated with it.
