Mario Hamuy, Carnegie Observatories, reports that a spectrum (range 380-730 nm)
of SN 2003cn, obtained on Mar. 31.31 UT with the Las Campanas Dupont 2.5-m 
telescope (+ Mod. Spec.), shows that this is a Type II supernova characterized
by Balmer lines exhibiting P-Cygni profiles, although the absorption component
of H alpha is very weak. The expansion velocity of 5900 km/s derived from the
minimum of H beta (assuming the NED recession velocity of 5430 km/s for the
host galaxy) and the weak He I 587.6 nm line suggest that SN 2003cn is about
2-3 weeks old.  

A spectrum of SN 2003bw obtained on Mar. 31.39 shows that this is
a Type II supernova, at least two months old.
