     V. Benishek, Belgrade Astronomical Observatory; P. Pravec, Ondrejov
Observatory; and R. Durkee, Shed of Science South Observatory, Pontotoc, TX,
U.S.A., report that photometric observations taken with a 0.35-m telescope at
the Sopot Observatory in Serbia and a 0.50-m telescope at the Shed of Science
South Observatory during Jan. 26-Mar. 4 reveal that minor planet (9010) is a
binary system with an orbital period of 12.958 +/- 0.003 hr.  The primary
shows a period of 3.1349 +/- 0.0005 hr and has a lightcurve amplitude of 0.10
magnitude at solar phases 2-6 degrees, suggesting a nearly spheroidal shape.
Mutual eclipse/occultation events that are 0.06 magnitude deep indicate a
secondary-to-primary mean-diameter ratio of 0.24 +/- 0.02.
