V. Benishek, Belgrade Astronomical Observatory; and P. Pravec, Ondrejov
Observatory, report that photometric observations taken with a 0.35-m
telescope at the Sopot Observatory in Serbia during 2023 Dec. 17-2024 Feb. 14
reveal that minor planet (2080) is a binary system with an orbital period of
25.83 +/- 0.01 hr. The primary shows a period of 2.7088 +/- 0.0002 hr and
has a lightcurve amplitude of 0.17 mag at solar phases 4-7 degrees,
suggesting a nearly spheroidal shape. Mutual eclipse/occultation events that
are 0.09 magnitude deep indicate a secondary-to-primary mean-diameter ratio
of 0.29 +/- 0.02.
