Department of Earth System Science and Policy, University of North
Dakota, Grand Forks; and R. Dyvig, Quinn, SD, report that photometric
observations obtained during 2006 Dec. 11-27 reveal that minor planet
(3073) is a binary system with an orbital period of 44.96 +/- 0.02 hr.
The primary shows a period of 3.4468 +/- 0.0001 hr, and it has a
lightcurve amplitude of 0.21 mag.  Mutual eclipse/occultation events that
are 0.06- to 0.07-mag deep indicate a secondary-to-primary mean-diameter
ratio of 0.25 +/- 0.02.
