Mario Hamuy and Mark Phillips, Carnegie Observatories, reports that a spectrum
(range 370-900 nm) of SN 2003em, obtained on Jun. 4.42 UT  with the Las Campanas
Observatory Clay 6.5-m telescope telescope (+ LDSS-2), shows that this is a 
Type Ia supernova about 40 days past maximum.

A spectrum of SN 2003ev obtained with the same instrument on June 4.19
shows a relatively featureless red continuum with broad ondulations.
The main features are broad emissions near H alpha and 457 nm, and
a trough centered around 570 nm possibly due to He I and Na I D.
These features are consistent with a highly reddened young Type Ic,
but a definitive classification will require additional observations.
Superimposed narrow emission H alpha emission from the host galaxy
yields a redshift of 0.024.

A spectrum of SN 2003ey obtained on June 4.27 shows that this is a
Type Ia supernova. The spectrum bears strong resemblance to that
of SN 1994D taken 5 days past maximum. By comparison to SN 1994D
an approximate redshift of 0.065 is derived.


A spectrum of SN 2003ez taken on Jun. 4.13 UT shows that this is
Type Ia supernova. The spectrum bears strong resemblance to that
of SN 1994D taken 3 days before maximum, although the Si II 635.5 nm
in SN 2003ez is weaker. The minimum of the Si II 635.5 nm
line yields an expansion velocity of -10200 km/s (adopting the NED
host-galaxy recession velocity of 14343 km/s).
