Mark Phillips and Mario Hamuy, Carnegie Observatories, report that a spectrum
(range 380-930 nm) of SN 2003xx in NGC 4316, obtained on Mar. 3.28 UT 
with the Las Campanas Dupont 2.5-m telescope (+ WFCCD), shows that this is
a highly reddened Type II supernova characterized by a red continuum with 
a strong H alpha line exhibiting a P-Cygni profile. The minimum of the H alpha
absorption yields an expansion velocity of 7600 km/sec, assuming the NED
recession velocity of 1252 km/sec for the host galaxy. 

A spectrum taken with the same instrument of SN 2003YY in NGC 5374 on
Mar. 3.35 shows that this is a young Type II supernova with a spectrum
characterized by a blue continuum, weak P Cygni Balmer lines and He I 587.6 nm.
The minimum of the H beta absorption yields an expansion velocty of 6300 km/sec,
assuming the NED recession velocity of 4295 km/sec for the host galaxy.
