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.
