2006IAUC.8707....2F

R. J. Foley, J. M. Silverman, M. Moore, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 330-1040 nm), obtained on May 5 UT with the Lick 3-m telescope (+ Kast), shows that SNe 2006bq and 2006bu (cf. IAUC 8705) are of type Ia at about 20 and 0 days past maximum brightness, respectively. Spectra of SNe 2006by and 2006ca reveal they are both of type II. The spectrum of SN 2006ca shows a very blue continuum with weak Balmer absorption lines, indicating that it is a young object. After removing the recession velocity of 5680 and 2670 km/s determined from narrow emission lines, the minima of the H_alpha P-Cyg absorption is seen to have velocities of 7600 and 17200 km/s for SNe 2006by and 2006ca, respectively. A spectrum of SN 2006bz shows it to be of type Ia, resembling SN 1991bg (Filippenko et al. 1992, A.J. 104, 1543) at maximum light; removing the host-galaxy recession velocity of 8366 km/s (Caldwell et al. 1992, A.J. 106, 473), the minimum of the Si II 6150 absorption is measured to be 10800 km/s.
