a very strong radar target at both Goldstone and Arecibo. The asteroid will approach from the

south and enter Goldstone's declination range on May 28 and Arecibo's on June 5. We are

planning an extensive campaign of observations at both observatories.

We hope to achieve resolutions as fine as 3.75 m. During some of the observations, we hope to

uplink 3.75 m chirps for reception at Arecibo. Arecibo monostatic observations should

obtain resolutions as fine as 7.5 meters.
