SUPERNOVAE 2006ek, 2006el, 2006em, AND 2006ep
     A. V. Filippenko, R. Chornock, R. J. Foley, D. S. Wong, M.
Ganeshalingam, and M. Moore, University of California, Berkeley,
report that inspection of CCD spectra (range 330-1040 nm), obtained
on Sept. 2 UT with the Shane 3-m telescope (+ Kast) at Lick
Observatory, shows that SN 2006ek (cf. IAUC 8741) if of type II,
with a host-galaxy recession velocity of 6040 km/s; the broad H-alpha
emission greatly dominates over the H-alpha absorption component.
SN 2006el (cf. IAUC 8741) appears to be of type IIb, near maximum
brightness (e.g., SN 1987K; Filippenko 1988, A.J. 96, 1941); broad
H-alpha emission is weak, but H-alpha absorption is prominent. (This
classification differs somewhat from that suggested by Blondin et al.
on CBET 612).  SN 2006em (cf. IAUC 8741) is a peculiar type-Ia
supernova, similar to SN 1991bg (Filippenko et al. 1992, A.J. 104,
1543), in agreement with Blondin et al. (CBET 612).  SN 2006ep (cf.
CBET 609) is of type Ib/Ic, a few days before maximum brightness,
again in general agreement with Blondin et al. (CBET 612).
