Binary asteroid discovery IAU announcement

IAU CBET nº4440:

V. Benishek, Belgrade Astronomical Observatory; P. Pravec, P. Kusnirak, 
and H. Kucakova, Ondrejov Observatory; F. Pilcher, Organ Mesa Observatory, 
Las Cruces, NM, U.S.A.; D. Pray, Sugarloaf Mountain Observatory, South 
Deerfield, MA, U.S.A.; R. Durkee, Shed of Science Observatory, Minneapolis, 
MN, U.S.A.; A. Aznar, Astronomia Para Todos Observatories Group, «European 
Near Earth Asteroids Research» (EURONEAR) project, Spain; and F. J. Aceituno, 
Observatorio de Sierra Nevada, report that photometric observations taken 
with a 0.35-m telescope at the Sopot Observatory in Serbia, a 0.65-m telescope 
at the Ondrejov Observatory, a 0.35-m at the Organ Mesa Observatory, a 0.50-m 
telescope at the Sugarloaf Mountain Observatory, a 0.50-m telescope at the 
Shed of Science Observatory, and a 0.9-m telescope at the Observatorio de 
Sierra Nevada during Aug. 27-Sept. 28 reveal that minor planet (10132) is a 
binary system with an orbital period of 22.44 ± 0.01 hr. The primary shows 
a period of 2.5099 ± 0.0001 hr and has a lightcurve amplitude of 0.11 mag 
at solar phases 2-3 degrees, suggesting a nearly spheroidal shape. Mutual 
eclipse/occultation events that are 0.08- to 0.16-magnitude deep indicate a 
lower limit on the secondary-to-primary mean-diameter ratio of 0.28.
