Mario Hamuy, Carnegie Observatories, reports that a spectrum (range 370-900 nm)
of SN 2003cx, obtained on Apr. 10.39 UT  with the Las Campanas Observatory
Clay 6.5-m telescope telescope (+ LDSS-2), shows that this is a normal
Type II supernova characterized by Balmer lines exhibiting P-Cygni profiles.
The expansion velocity of -10000 km/s derived from the minimum of H alpha
(based on a redshift of 0.037, derived for the host galaxy from
superimposed narrow emission Balmer lines) and the relatively blue continuum
suggest that SN 2003cx is about 2-3 weeks old.  

A spectrum of SN 2003dc taken on Apr. 10.37 UT shows that this is
Type Ia supernova near maximum light. The minimum of the Si II 635.5 nm
line yields an expansion velocity of -10060 km/s (based on a redshift of
0.067, derived for the host galaxy from superimposed narrow H alpha
emission).
