(2966) KORSUNIA
     V. Benishek, Belgrade Astronomical Observatory; P. Pravec and P.
Kusnirak, Ondrejov Observatory; F. Vachier, Observatoire de Paris; and A.
Klotz, P. Thierry, and J. Berthier, Observatoire des Makes, Reunion, report
that photometric observations taken with a 0.35-m telescope at the Sopot
Observatory in Serbia and a 0.6-m telescope at the Observatoire des Makes
during Apr. 20-May 23 reveal that minor planet (2966) is a binary system with
an orbital period of 17.521 +/- 0.004 hr.  The primary shows a period of
2.31419 +/- 0.00007 hr and has a lightcurve amplitude of 0.12 mag at solar
phases 6-21 degrees, suggesting a nearly spheroidal shape.  Mutual
eclipse/occultation events that are 0.06 magnitude deep indicate a
secondary-to-primary mean-diameter ratio of 0.24.
