L. A. Helton, T. Vonderharr, and C. E. Woodward, University of Minnesota; and G. J. Schwarz, American Astronomical Society, report on Boller-and-Chivens spectroscopic observations (range 380-930 nm; resolution about 0.28 nm) of this object, obtained at the Steward Observatory Bok 2.29-m telescope on Apr. 25.4 UT. These observations confirm that this is a post-maximum classical nova. The spectra exhibit strong, broad H_alpha emission (FWHM about 4000 km/s) with a flux of F = 1.4 x 10**-11 erg/s/cm**2. No other emission lines are readily apparent blueward of H_alpha. Permitted emission from O I 844.6-nm (FWHM about 3350 km/s; F = 1.7 x 10**-11 erg/s/cm**2) and 777.3-nm (FWHM about 3400 km/s) dominates the red spectrum. H_alpha and O I 777.3-nm both have asymmetric line profiles with a single blue peak. The emission lines are superimposed on a continuum that rises sharply to the red. The lack of any blue emission lines in the spectrum, along with the climbing red continuum, suggests that this object is subjected to an exceptionally high degree of extinction. The red spectrum is similar to that of Nova Pup 1991 (V351 Pup; Williams et al. 1994, Ap.J. Suppl. 90, 297), which suggests that the remaining features dominating the red spectrum are likely due to multiplet emission from Mg II (1,7,8), N I (1,2,15), and Na I (19).
