G. Ruch, E. Polomski, and C. E. Woodward, University of Minnesota; R. M. Wagner, LBT Observatory; and S. Starrfield, Arizona State University, report that optical spectra (range 370-640 nm, resolution 0.6 nm) were obtained with the Steward Observatory Bok 2.3-m telescope on Kitt Peak on Sept. 19.10 UT, showing that the spectrum of Brown's object exhibits emission lines of H_beta (equivalent width 0.6 nm), H_gamma, H_delta and numerous Fe II lines with P-Cyg profiles superposed on a flat continuum. The FWHM of H_beta emission is 612 km/s, and the terminal velocity of the absorption component is 800 km/s. The equivalent width of the diffuse interstellar line at 578 nm is 0.05 nm, corresponding to E(B-V) about 0.1 mag. The spectra confirm that this object is an Fe-II-class nova in its early decline stage.
