(10044) SQUYRES
     V. Benishek, Belgrade Astronomical Observatory; P. Pravec, Ondrejov
Observatory; and R. Durkee, Shed of Science South Observatory, Pontotoc, TX,
U.S.A., report that photometric observations taken with a 0.35-m telescope at
the Sopot Observatory in Serbia and a 0.50-m telescope at the Shed of Science
South Observatory during 2022 Aug. 12-Nov. 30 reveal that minor planet (10044)
is a binary system with an orbital period of 18.67 +/- 0.01 hr.  The primary
shows a period of 3.3356 +/- 0.0005 hr and has a lightcurve amplitude of 0.10
magnitude at solar phases 17-18 degrees, suggesting a nearly spheroidal shape.
Mutual eclipse/occultation events that are 0.08 to 0.16 magnitude deep
indicate a lower limit on the secondary-to-primary mean-diameter ratio of 0.28.
