Further to ATel#5456, here we report the spectroscopic classification of five CRTS
supernova candidates using Palomar 5m+DBSP on 2013 Nov 09 UT.
Classification of SN-Ia was performed via SN spectrum cross correlation
using SNIDs (Blondin & Tonry, 2007, ApJ, 666, 1024).

Notes:
(a) The redshift was determined from narrow emission lines in the strongly starforming host galaxy.
(b) This is a moderately energetic SN-IIn discovered in 2012 (Drake et al. 2013, ATel#4733).
