1994 XD Goldstone Radar Observations Planning
1994 XD is a binary near-Earth asteroid that was discovered by Spacewatch (Kitt Peak, AZ) on December 1, 1994. It was imaged at coarse resolution and relatively modest SNRs at Arecibo in 2005, which revealed the presence of a satellite, but the previous radar observations were insufficient to estimate the orbital parameters of the system or a shape model for either component. The 2005 Arecibo images suggest that the primary is roughly 0.6 km in diameter and place an upper bound on its rotation period of 4.2 hours. We don't have a detailed estimate for the diameter of the secondary. The spectral class is unknown. To the best of our knowledge, there are no lightcurves, so a more precise estimate of the rotation period is not available either. The S-band circular polarization ratio SC/OC = 0.21. 1994 XD will approach within 0.052 AU (20 lunar distances) on Nov. 27, 2012. It will be moderately strong radar target at Goldstone and we hope to obtain images with resolutions as fine as 0.5 usec. Time to observe 1994 XD has also requested at Arecibo, where it should be a strong imaging target. 1994 XD will be too close to the Sun for most of the fall for optical observations, so there may not be any more ephemeris updates before the radar tracks. It will be a good target for lightcurves and spectroscopy shortly after the radar observations start.

Although the 1994 XD tracks overlap 2007 PA8 view periods, we are expecting 1994 XD to be
about twice as strong, so we don't plan any more observations of 2007 PA8.

From Jon Giorgini, Nov 27: Three new optical measurements reported by Cerro Tololo Observatory (site 807) were used to update 1994 XD to orbit solution #36, now on aardvark. The new data differed from/corrected the prediction of s34 by ~5", so a sub-sigma change in pointing. Formal 3-sigma .s36 S/X-band uncertainties.

Due to its 4.2-hour rotation period and estimated size, we are expecting a bandwidth of about 14 Hz.
The SNRs should be strong enough to see an echo relatively quickly, so we'll start with a setup
with 0.98 Hz resolution, and then we'll switch to ranging, and, we hope, coarse-resolution imaging.
