\nNevada, Instituto de Astrofisica de Andalucia, Consejo Superior de
\nInvestigaciones Cientificas, report that photometric observations taken with a
\n0.35-m telescope at the Sopot Observatory in Serbia, a 0.65-m telescope at the
\nOndrejov Observatory, a 0.70-m telescope at the Chuguev station of the Kharkiv
\nObservatory in Ukraine, a 0.35-m telescope at the Organ Mesa Observatory, and
\na 0.90-m telescope at Sierra Nevada Observatory during Sept. 18-Oct. 15 reveal
\nthat minor planet (2178) is a binary system with an orbital period of 18.504
\n\u00b1 0.006 hr. The primary shows a period of 3.0183 \u00b1 0.0002 hr and has a
\nlight-curve amplitude of 0.31 mag at solar phases 8-11 degrees. Mutual
\neclipse\/occultation events that are 0.07 to 0.15 magnitude deep indicate a
\nsecondary-to-primary mean-diameter ratio of 0.26 \u00b1 0.02. The secondary
\nappears synchronous and has a light-curve amplitude (in the combined primary
\nplus secondary light curve) of 0.02 mag, suggesting a moderately elongated
\nshape with the equatorial axis ratio of 1.3 \u00b1 0.1.<\/p>\n
