Referred to by ATel #: 5465, 5590

Further to ATel#5437, here we report the spectroscopic classification of 16 CRTS supernova candidates using Palomar 5m+DBSP on 2013 Oct 06 UT.
Classifications were performed via SN spectrum cross correlation using SNIDs (Blondin & Tonry, 2007, ApJ, 666, 1024).

Notes: 
(a) Redshift was determined from narrow emission lines in the host galaxy. 
(b) Discovery announced in Drake et al. (2013, ATel#5437). 
(c) Low S/N spectrum. 
Analysis of two additional SN is underway. Links to all CRTS transients can be found at http://crts.caltech.edu/.
