(14469) KOMATSUATAKA
     V. Benishek, Belgrade Astronomical Observatory; and P. Pravec, Ondrejov
Observatory, report that photometric observations taken with a 0.35-m
telescope at the Sopot Observatory in Serbia during Sept. 12-Oct. 18 reveal
that minor planet (14469) is a binary system with an orbital period of 19.32
+/- 0.01 hr.  The primary shows a period of 2.6226 +/- 0.0002 hr and has a
lightcurve amplitude of 0.13 magnitude at solar phases 5-12 degrees,
suggesting a nearly spheroidal shape.  Mutual eclipse/occultation events
that are 0.06 to 0.10 magnitude deep indicate a secondary-to-primary mean-
diameter ratio of 0.24 +/- 0.02.
