We conducted a spectroscopic observation of transient PS15aez (Atel #7437) at
2015-04-23T23:18:42 UT. One spectrum was obtained in the visible (400-800nm) with resolution
R~350 using the SPRAT spectrograph on the Liverpool Telescope located at
Roque de los Muchachos. Classification using SNID (Blondin & Tonry 2007,
ApJ, 666, 1024) indicates it is a type Ia SN near maximum with closest
matching spectrum SN2007S. The redshift is estimated as z=0.056. SiII expansion velocity is estimated at 11300
km/s.
