(6265) 1985 TW3
     D. Higgins, Canberra, Australia; and P. Pravec and P. Kusnirak, Ondrejov
Observatory, report that photometric observations obtained during July 15-25
reveal that minor planet (6265) is a binary system with an orbital period of
15.86 +/- 0.01 hr.  The primary shows a period of 2.7091 +/- 0.0001 hr, and
it has a lightcurve amplitude of 0.28 mag.  Mutual eclipse/occultation events
that are 0.06- to 0.12-mag deep indicate a lower limit on the secondary-to-p
rimary mean-diameter ratio of 0.24 +/- 0.02.
