Mario Hamuy, Carnegie Observatories, reports that a spectrum (range 380-930 nm)
of SN 2003cv, obtained by Jose Maza and L. Huerta (Univ. Chile) on Apr. 6.15 UT
with the Las Campanas Dupont 2.5-m telescope (+WFCCD), shows that this is a 
peculiar Type II supernova. The spectrum is characterized by Halpha and
Hbeta lines exhibiting very broad P-Cygni profiles. The minima of these
lines yield expansion velocities of 14,000 and 11,300 km/s (based on a
redshift of 0.028 derived for the host galaxy from superimposed narrow
Balmer lines), which are unusually high for Type II supernovae.
The spectrum is also characterized by a broad trough centered at 589.1 nm,
probably due to Na I D 589.3 nm, and by a P-Cygni profile due to 
the Ca II near-infrared triplet. This spectrum is very similar to
that of the H-rich "hypernova" SN 2003bg (IAUC 8084 and 8088)
taken on Apr 4.04 UT by Maza and Huerta, which suggests that
SN 2003cv is at least least one month old.
