We conducted a spectroscopic observation of transient PSN J13332289+5843315 at 2015-04-16T01:24:24 UT.
This transient was identified as a possible SN by S. Maticic at the Crni Vrh Observatory at
2015-04-01T22:12:00 UT.
We obtained a spectrum 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 and Tonry 2007, Ap.J. 666, 1024) indicates it is a normal type Ia SN with a close match to the spectrum of SN2004er. Age is estimated at +19 days post maximum. Estimated redshift, z = 0.030.
