We report the spectroscopic confirmation of CSS150325:140426+514417 (the candidate has been selected among those released
by the Catalina Real-Time Transient Survey; see http://crts.caltech.edu/ ) through observations obtained with the 1.82-m
Copernico Telescope of the Asiago Astronomical Observatory (+ AFOSC; range 340-820 nm, resolution 1.3 nm).
A spectrogram of CSS150325:140426+514417 obtained on March 30.94 UT shows it is likely a Type Ic supernova.
Adopting for the anonymous host galaxy an approximate redshift z = 0.046, as inferred from the position of the
most prominent lines, a good match is found with the Type Ic SN 2004aw (Taubenberger et al. 2006, MNRAS, 371, 1459),
a few days after the maximum light.
The Asiago classification spectra are posted at this website: URL http://sngroup.oapd.inaf.it. The classification was made
using the GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) tools.
