We report spectroscopic classification of PSN J11473508+5558147 through inspection of a low-dispersion optical spectrum (range 370-680 nm), obtained with the 2.3-m Bok telescope (+ Boller & Chivens spectrograph) at Kitt Peak on 2015 June 21 UT. Information on this transient, discovered by P. Wiggins, was announced through the CBAT Transient Object Followup Reports (http://www.cbat.eps.harvard.edu/index.html) and is also available from the "Bright Supernova" website (http://www.rochesterastronomy.org/snimages/).
PSN J11473508+5558147 is a Type Ib supernova; cross-correlation with a library of supernova spectra using the comparison tool GELATO (Harutyunyan et al. 2008, A&A, 488, 383) finds good matches with near-maximum Type-Ib supernovae at a redshift of 0.008, consistent with the NED redshift of the putative host galaxy, NGC 3888 (de Vaucouleurs et al., 1991, RC3 catalogue).
