     D. Higgins, Canberra, Australia; D. Pray, Carbuncle Hill
Observatory, Greene, RI; P. Kusnirak and P. Pravec, Ondrejov
Observatory, report that photometric observations obtained during
Sept. 26-Oct. 17 reveal that minor planet (6244) is a binary system
with an orbital period of 20.32 +/- 0.01 hours.  The primary rotates
with a period of 2.8958 +/- 0.0001 hours, and it has a lightcurve
amplitude of 0.11 mag.  Mutual eclipse/occultation events that are
0.07-0.15 mag deep indicate a secondary-to-primary mean-diameter
ratio of 0.25 +/- 0.02.
