\nAstronomical Observatory of the University of Siena, a 0.35-m telescope at the

\nObservatory, a 0.50-m telescope at the Shed of Science South Observatory, a
\n0.50-m telescope at the Sonoita Research Observatory, a 0.35-m telescope at
\nthe Linhaceira Observatory, a 0.35-m telescope at the Isaac Aznar Observatory,
\nand a 0.50-m telescope at the Mittelman Observatories at New Mexico Skies
\nduring Mar. 20-May 19 reveal that minor planet (2500) is a binary system
\nwith an orbital period of 169.1 \u00b1 0.3 hr. The primary shows a period of
\n2.75123 \u00b1 0.00009 hr and has a lightcurve amplitude of 0.19 magnitude at
\nsolar phases 2-17 degrees, suggesting a nearly spheroidal shape. Mutual
\neclipse\/occultation events that are 0.15 to 0.27 magnitude deep indicate a
\nsecondary-to-primary mean-diameter ratio of 0.39 \u00b1 0.02.<\/p>\n
