Silverman, C. V. Griffith, A. V. Filippenko, R. Chornock, and W. Li, University of California, Berkeley, report that inspection of CCD spectra (range 330-1030 nm), obtained on July 26 UT with the Shane 3-m reflector (+ Kast spectrograph) at Lick Observatory, shows that 2008dv (CBET 1425) is a type-Ic supernova roughly two months past maximum brightness; the spectrum resembles that of SN 2007iq (CBET 1101). SN 2008dz (CBET 1430) is a type-II supernova; removing a recession velocity of 8100 km/s (from narrow emission lines), the minimum of the H-alpha absorption is blueshifted by about 7800 km/s. SN 2008ee (CBET 1440) is a type-Ia supernova, nearly two months past maximum. SN 2008ei (CBET 1446) is also a type-Ia supernova. Cross-correlation with a library of type-Ia-supernova templates using the SNID code (Blondin and Tonry 2007, Ap.J. 666, 1024) gives a best-fit age for 2008ei of 2.1 +/- 4.5 days before maximum brightness; removing a host-galaxy recession velocity of 11284 km/s (de Vaucouleurs et al. 1991, Third Reference Catalogue of Bright Galaxies), the minimum of the Si II 635.5-nm absorption feature is found to be blueshifted by about 15300 km/s.
