Arecibo Observatory; M. K. Shepard, Bloomsburg University of
Pennsylvania; J. D. Giorgini and S. J. Ostro, JPL; M. W. Busch,
California Institute of Technology; and A. A. Hine, Arecibo Observatory,
report that Arecibo and Goldstone delay-Doppler radar observations of
2006 GY2 on May 15-16 show that this Apollo-type minor planet (cf.
MPEC 2006-G37) is a binary system. Preliminary estimates for the
diameters are 400 m for the primary and 80 m for the secondary. The
maximum orbital distance between the components is at least 500 m.
