\nV. Benishek, Belgrade Astronomical Observatory; P. Pravec, H. Kucakova,
\nK. Hornoch, and P. Kusnirak, Ondrejov Observatory; A. Aznar, Isaac Aznar
\nObservatory, Alcublas, Valencia, Spain; A. Leroy, Association T60, Toulouse,
\nFrance; and R. Durkee, Shed of Science South Observatory, Pontotoc, TX, USA,
\nreport that photometric observations taken with a 0.35-m telescope at the
\nSopot Observatory in Serbia, a 0.65-m telescope at the Ondrejov Observatory,
\na 0.35-m telescope at the Isaac Aznar Observatory, a 0.50-m telescope at Pic
\ndu Midi Observatory, and a 0.50-m telescope at the Shed of Science South
\nObservatory during Jan. 14-Mar. 27 reveal that minor planet (4494) is a
\nbinary system with an orbital period of 24.73 \u00c2\u00b1 0.02 hr.\u00a0 The primary
\nshows a period of 4.1209 \u00c2\u00b1 0.0002 hr and has a lightcurve amplitude of 0.12
\nmagnitude at solar phases 0.4-10.5 degrees, suggesting a nearly spheroidal
\nshape.\u00a0 Mutual eclipse\/occultation events that are 0.15 magnitude deep
\nindicate a lower limit on the secondary-to-primary mean-diameter ratio of
\n0.38.\u00a0 The mean absolute R magnitude in the Cousins system is H_R = 13.28
\n\u00c2\u00b1 0.15, assuming the phase-relation slope parameter G = 0.24 \u00c2\u00b1 0.11.<\/p>\n
