Mark Phillips, Carnegie Observatories, reports that a spectrum (range 360-900 nm)
of SN 2003XX (R.A. = 11h33m24s.50, Decl. = -9 59'26".4), obtained on May 5.10 UT
with the Las Campanas Observatory Clay 6.5-m telescope telescope (+ LDSS-2), shows
that this is a Type IIn supernova characterized by a blue continuum and strong
Balmer lines in emission, at a redshift of 0.021.

A spectrum of SN 2003dq taken on May 5.06 shows that this is a type
II supernova with Balmer lines exhibiting P-Cygni profiles, although the
H-alpha absorption is very weak. The expansion velocity of -7800 km/s
derived from the minimum of H alpha (based on a redshift of 0.046, derived
for the host galaxy from superimposed narrow emission Balmer lines) 
suggest that SN 2003dq is several weeks old. 

A spectrum of SN 2003ec taken on May  5.33 UT shows a blue, featureless
continuum.

A spectrum of SN 2003dt taken on May 5.35 UT shows that this is a Type Ia
supernova about 3 months past maximum light.
