SUPERNOVAE 2003fe, 2003ff, 2003fg, 2003fh, 2003fi, 2003fj, 2003fk
     R. Ellis, California Institute of Technology; M. Sullivan,
University of Durham; and P. Nugent, Lawrence Berkeley National
Laboratory, report on CCD spectra (range 360-950 nm) of the Legacy
Survey supernovae announced on IAUC 8147, obtained during Apr. 2-6
(Keck II + DEIMOS) and on Apr. 7, May 6, June 1, and 2 (Keck I +
LRIS).  Host-galaxy redshifts were measured using the [O II]
372.7-nm line or the Ca II H and K lines, and the supernova
features were consistent with these redshifts.  The epochs for the
six type-Ia supernovae (all except SN 2003fe) are based on a
comparison of the spectroscopic features with the templates
described by Nugent et al. (2002, PASP 114, 803).  SN 2003fe (Apr.
2) is of type II, with a redshift of 0.42 (at early epoch, with a
featureless blue spectrum).  Redshifts of the type-Ia supernovae
(which were all near peak brightness, with SNe 2003fh and 2003fi
observed a week before peak):  SN 2003ff, 0.50 (Apr. 3, 6, 7); SN
2003fg, 0.24 (May 6); SN 2003fh, 0.25 (May 6); SN 2003fi, 0.44
(June 1, 2); SN 2003fj, 0.47 (June 2); SN 2003fk, 0.35 (June 1).

apparent supernovae during the CFHT Legacy Survey:

1 week before peak brightness); SN 2003fp, Ia, 0.45 (May 6; near
peak brightness).
