We report the spectroscopic classification of four supernovae at the 2.5m Isaac Newton Telescope on La Palma, using the Intermediate Dispersion Spectrograph and the R300V grating (3500-8000 Ang; ~6 Ang resolution). Observations were made on 3 September 2014, and targets were selected from the Catalina Real Time Transient Survey (CRTS; Drake et al. 2009, ApJ, 696, 870), the MASTER survey (ATel #6434, http://observ.pereplet.ru/ ) and from the CBAT Transient Object Confirmation Page.
