TOO - Interferometric Radar Observations of Asteroid 2006 VV2

Near Earth asteroid 2006 VV2 will approach the Earth to within 0.024 AU in late March-early April 2007 at which time we request a short session to image and do astrometry of this asteroid while it's illuminated by the Arecibo S-Band radar system. We request 30 min of transmit only time on 2007 April 1. A companion proposal has been submitted for matching time at the VLBA and GBT to receive the asteroid's radar echo. Synthesis radar imaging can provide plane-of-sky image and position information orders of magnitude better than other ground-based methods, and which is complementary to standard radar mapping. The asteroid's diameter is likely between 1.5 and 2 km, and we expect a spatial resolution of order 50 m. In addition, by resolving the asteroid's echo in frequency during correlation, we can determine the absolution orientation of its shape and rotation axis.
