Rabinowitz, and A. Bauer, Yale University) reports that a spectrum (range 320-1000 nm) of SN 2005db (cf. CBET 182), obtained July 20.6 UT with the Supernova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, shows it to be a type-IIn supernova. The spectrum is blue and featureless, save for narrow emission lines of H_alpha and H_beta of approximately 400 km/s (FWHM) – adopting the NED recession velocity of 4534 km/s for the host galaxy (from Giovanardi and Salpeter 1985, Ap.J. Suppl. 58, 623), this velocity confirmed from the spectrum of SN 2005db. The narrow H_alpha emission line sits on top of a broader component that is approximately 1600 km/s (FWHM).
