Urgent Proposal for S-band Radar Imaging of Near-Earth Asteroid 2008 BT18

in July 2008
ABSTRACT:
We propose delay-Doppler radar imaging, physical modeling, satellite searches, and orbit refinement of near-Earth asteroid 2008 BT18 during its very close approach within 0.015 AU (6 lunar distances), when it will be an extremely strong imaging target. With an absolute magnitude H = 18.3, 2008 BT18 is probably within a factor of two of 700 meters in diameter, so 7.5-m delay-Doppler images could place thousands of pixels on the ob ject and reveal considerable surface detail.
