Kusnirak, and P. Pravec, Ondrejov Observatory; V. Chiorny and Yu. Krugly,

Kharkiv Observatory; M. Husarik and M. Pikler, Skalnate Pleso

Observatory; F. Marchis, B. Macomber, and M. Kislak, SETI Institute and

University of California at Berkeley; and J. Vilagi and S. Gajdos, Modra

Observatory, report that photometric observations obtained during Apr. 16

to May 3 reveal that minor planet (6708) is a binary system with an

orbital period of 24.7 hr. The primary shows a period of 8.221 +/- 0.002

hr, assuming a bi- modal lightcurve, and it has a lightcurve amplitude of

0.08 mag, suggesting a nearly spheroidal shape. Mutual

eclipse/occultation events with a depth of 0.31 mag indicate a lower

limit on the secondary-to-primary mean-diameter ratio of 0.57. The mean

absolute R-band magnitude of the system is H = 12.81 +/- 0.14, assuming G

= 0.25 +/- 0.2.
