that photometric observations taken with a 0.35-m telescope at the Sopot
Observatory in Serbia, a 0.61-m telescope at the Skalnate Pleso Observatory,
a 0.30-m telescope at the Astronomical Observatory of the University of Siena,
a 0.23-m telescope at the Wild Boar Remote Observatory, a 0.50-m telescope at
the Starry Night Observatory, a 0.90-m telescope at the Sierra Nevada
Observatory of the IAA, a 0.35-m telescope at the IPT's Linhaceira
Observatory, and a 0.50-m telescope at the Shed of Science South Observatory
during Mar. 2-May 16 reveal that minor planet (3523) is a binary system with
an orbital period of 29.26 +/- 0.02 hr.  The primary shows a period of 2.6742
+/- 0.0001 hr and has a lightcurve amplitude of 0.08 magnitude at solar
phases 9-13 degrees, suggesting a nearly spheroidal shape.  Mutual eclipse/
occultation events that are 0.06 magnitude deep indicate a lower limit on the
secondary-to-primary mean-diameter ratio of 0.24.
