J. Oey, Blue Mountains Observatory, Leura, NSW, Australia; P. Pravec, H.
Kucakova, and K. Hornoch, Ondrejov Observatory; V. Benishek, Belgrade
Astronomical Observatory; and A. Marchini, R. Papini, and F. Salvaggio,
Dipartimento di Scienze Fisiche, Della Terra e Dell'Ambiente, University of
Siena, report that photometric observations obtained with a 0.50-m telescope
at the Sugarloaf Mountain Observatory, a 0.35-m telescope at the Blue
Mountains Observatory, a 0.65-m telescope at the Ondrejov Observatory,
a 0.35-m telescope at the Sopot Observatory in Serbia, and a 0.30-m
telescope at the Astronomical Observatory of the University of Siena during
July 16-Sept. 25 reveal that minor planet (23621), whose orbit crosses that
of Mars, is a binary system with an orbital period of 20.60 ± 0.03 hr.
The primary shows a period of 2.6649 ± 0.0005 hr and has a lightcurve
amplitude of 0.07 mag at solar phases 1-4 degrees, suggesting a nearly
spheroidal shape. Mutual eclipse/occultation events that are 0.04- to
0.12-magnitude deep indicate a lower limit on the secondary-to-primary
mean-diameter ratio of 0.27.

31170 1997 WO58
PSABA target
This one turned out to be a tough target. It was not such long period as I
thought it might have been originally and the poor weather condition here meant I
couldn't get long sessions .
The Jan and Feb data pointed to a shorter 13.7h period and
0.3mag amplitude. However I have to adjust 12/09 and 01/20 by as much a
0.5mag. which I concluded to be stray . Once adjusted, the curve fit well into the 13.7h light curve
