     V. Benishek, Belgrade Astronomical Observatory; P. Pravec, Ondrejov
Observatory; D. Pray, Sugarloaf Mountain Observatory, South Deerfield, MA,
U.S.A.; O. Labrevoir, Saint-Michel l'Observatoire, France; A. Carbognani,
Astronomical Observatory of the Autonomous Region of the Aosta Valley, Italy;
R. Durkee, Shed of Science South Observatory, Pontotoc, TX, U.S.A.; and F.
Pilcher, Organ Mesa Observatory, Las Cruces, NM, U.S.A., report that
photometric observations obtained with a 0.35-m telescope at the Sopot
Observatory in Serbia, a 0.50-m telescope at the Sugarloaf Mountain
Observatory, a 0.58-m telescope at the Saint-Michel l'Observatoire, a 0.50-m
telescope at the Shed of Science South Observatory, and a 0.35-m telescope
at the Organ Mesa Observatory during 2018 Oct. 24-Dec. 18 reveal that minor
planet (2337) is a binary system with an orbital period of 16.09 +/- 0.01 hr.
The primary shows a period of 2.53163 +/- 0.00009 hr and has a light-curve
amplitude of 0.06 mag at solar phases 5-15 degrees, suggesting a nearly
spheroidal shape.  Mutual eclipse/occultation events that are 0.03-magnitude
deep indicate a lower limit on the secondary-to-primary mean-diameter ratio
of 0.16.
