R. Kotak, T.-W. Chen, and M. Fraser, Queen's University, Belfast, report that a spectrum (range 330-975 nm; resolution about 1000) of PSN J22415183+3458074 = SN 2012go was obtained on Nov. 20.81 UT with the 4.2-m William Herschel Telescope (+ ISIS). Cross-correlation with a library of supernova spectra via the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that SN 2012go is a young type-Ia supernova (with a best match to SN 2002dj) at phase of between -7 and -3 days from maximum light, and with a redshift of z = 0.03. The redshift measured from 2012go is in agreement with that measured from narrow emission lines from the host galaxy.
