Urgent Proposal for Radar Imaging of Near-Earth Asteroid 2005 EU2

We prop ose to obtain high-resolution (15m) imaging of near-Earth asteroid 2005 EU2 in March and April of 2005. Recent exp erience has shown that there is an enormous variety in the shap es, radar reflectivities, and rotation states of near-Earth asteroids. Go o d imaging opp ortunities for relatively small ob jects such as 2005 EU2 (100m diameter) o ccur only a few times p er year. Radar imaging can help determine the internal structure by giving us information ab out the size, spin rate and even density in the case of binary systems.
