M. Hicks, P. Weissman, A. Chamberlin, and S. Lowry, Jet Propulsion Laboratory, write: "We have obtained low-resolution CCD spectroscopy of 1998 SF_36 from 0.35 to 1.0 microns, using the Palomar 5-m Hale reflector on Mar. 17.43 UT. The object exhibits a spectrum dominated by olivine. The modest spectral slope between 0.55 and 0.70 microns (S = 8.0 +/- 0.3 percent per 100 nm) and deep 1-micron absorption (V-X = +0.19 +/- 0.003) suggests a classification of type QRS, similar to other small basaltic near- earth objects in the ECAS dataset (Cruikshank et al. 1991, Icarus 89, 1)."
