Further to ATel#4872, here we report the classification of CRTS supernova candidates using Palomar 5m+DBSP on 2013 March 4th, 15th and 19th UT. Classifications were done using SNIDs (Blondin & Tonry, 2007, ApJ, 666, 1024).

Notes: 
In addition, we observed SSS130304:114445-203141 on Mar 15th. This was found it to  
best match to luminous type Ia SN 2006gz (Maeda et al. 2009, ApJ, 690, 1745) in  
contrast to a normal Ia noted from the early spectrum of Inserra et al. (2013, ATel#4863). 
CSS130315:115252-185920 was also be confirmed to be a type-Ia by the CSP (private comm.).
