L. Magill, R. Kotak, and D. Wright, Queen's University, Belfast, report that optical spectra (320-990 nm) of PSN J03513452+3704427 = SN 2012B were obtained at the Isaac Newton Telescope (+ IDS) on Jan. 16.007 UT. The spectra were cross-correlated with a library of supernova spectra using the Supernova Identification tool (SNID; Blondin and Tonry, 2007, Ap.J. 666, 1024) and yielded the following results: 2012B is best fit with the normal type-Ia supernova 2002er (Kotak et al. 2005, A.Ap. 436, 1021) at an epoch of three days post-maximum light. An expansion velocity of 10000 km/s is measured from the Si II absorption feature found at 624 nm, corrected for the expansion velocity of the host galaxy, PGC 13981 (5199 km/s; Wegner et al. 1993, A.J. 105, 1251; via the NED database).
