Urgent Proposal for Arecibo Radar Imaging of near-Earth Asteroid 2006 GY2

We propose radar imaging of recently-discovered near-Earth asteroid 2006 GY2 during its close approach within 0.017 AU on 2006 May 15-16. The proximity of the close approach and the asteroid's diameter of about 550 m (+/a factor of two) suggest very strong signal-to-noise ratios of about 10,000 per run that will be ideal for resolving fine detail (at resolutions of 7.5 m/pixel) on the surface, searching for satellites, and improving the asteroid's orbit. We plan to use range-Doppler images obtained at Arecibo and Goldstone to reconstruct a detailed model of the asteroid's three-dimensional shape and spin state, which constrain the asteroid's origin and geologic history.
