M. Ganeshalingam, F. J. D. Serduke, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 330-1060 nm), obtained on Jan. 16 UT with the Shane 3-m reflector at Lick Observatory, reveals that SN 2004gz (IAUC 8460) is of type Ia, a few weeks past maximum brightness. SN 2005C (IAUC 8463) is probably of type Ib, several weeks past maximum; a set of He I absorption lines appears to be present. SN 2005G (IAUC 8465) is probably of type Ia near maximum, but the spectrum is somewhat peculiar (e.g., unusually narrow Si II 635.5-nm absorption; the two S II absorption lines near 550 nm are blended together); although the optical continuum is very blue, there is a sharp decline in flux density shortward of the Ca II H + K trough. A very noisy CCD spectrum, obtained on Jan. 17, suggests that SN 2004gx (IAUC 8459) is probably of type II. A broad emission feature at the wavelength of H_alpha is visible in the redshifted spectrum.
