(4492) Debussy

Further to IAUC 8265 and 8292, R. Behrend writes (on behalf of fourteen others) that photometric observations of (4492) obtained during 2002 Oct. 30-Dec. 4 and 2004 Mar. 18-May 18 show a regularly shaped lightcurve with period 1.108 day and amplitude 0.5 mag, with sharp attenuations characteristic of mutual eclipse/occultation events observed at minima of the regular lightcurve having depth about 0.6 mag and duration about 2.5 hr -- suggesting that this is probably a binary system, with properties similar to those of (1089) and (1313).
