Morrell, on behalf of the Carnegie Supernova Project (CSP), report that they have obtained spectra (range 380-920 nm) of 2008bm (cf. CBET 1320), 2008bp (cf. CBET 1326), and 2008bq (cf. CBET 1328) with the Las Campanas Observatory DuPont Telescope (+ WFCCD) on Apr. 7.1-7.3 UT. Supernova 2008bm appears to be a type-IIn supernova, a couple of months past explosion. The spectrum of 2008bm is nearly identical to a spectrum of the type-IIn supernova 2005kj taken by the CSP on 2006 Feb. 13.1. SN 2008bp appears to be a highly reddened young type-II-plateau supernova. The spectrum consists of a red continuum with strong H-alpha emission and a relatively weak H-beta absorption. Using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024), they find 2008bp to be similar to supernova 2004et around two weeks past explosion. Adopting a host-galaxy recession velocity of 2723 km/s (de Vaucouleurs et al., Third Reference Catalogue of Bright Galaxies, Version 3.9) for the host galaxy, NGC 3095, H-beta is measured to be blue-shifted by roughly 9000 km/s. The spectrum of 2008bq indicates that it is a type-Ia supernova near maximum light. With the aid of SNID, they find 2008bq to be similar to supernova 2003du at one day before maximum light. Adopting a host-galaxy recession velocity of 10193 km/s (derived from emission lines in a spectrum of the host galaxy), the Si II absorption feature yields an expansion velocity of roughly 11000 km/s.
