We estimate asteroid 1992 SK's shape from delay-Doppler images and (Doppler-only) echo spectra obtained during March 22-27, 1999 at Goldstone. The images are not very strong and span only ˜15 degrees of sky motion, but place up to 20 (40 m by 160 m) pixels on the asteroid. The spectra span ˜30 degrees of sky motion, providing additional geometric leverage to constrain the pole direction. The variation in radar cross-section and echo bandwidth is consistent with the 7.3 hour rotation period obtained from lightcurves. Our analysis establishes that the radar tracks are confined to subradar latitudes between 20-40 degrees, but have complete rotational phase coverage. The asteroid is ˜1.3 km in maximum extent and slightly asymmetric, with an elongation of ˜1.3.
