We report that an optical spectrum (range 490-950 nm) obtained on Nov 15.8 UT with the William Herschel Telescope, La Palma using the Auxiliary-port Camera (ACAM), confirms that iPTF13ebh (ATEL #5580) is a young Type Ia supernova. Using 'superfit' (Howell et al. 2005), the spectrum was found to be most similar to SN 1994d at -8 days. Adopting a redshift of 0.013269 for the host galaxy, NGC 890 (from NED), we estimate the Si II 6150 feature has a minimum at ~13000 km/s.
