L. Tomasella, S. Benetti, E. Cappellaro, A. Pastorello, P. Ochner, M. Turatto, and S. Valenti, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that a spectrogram of 2012bq, obtained on Mar. 31.81 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 340-820 nm; resolution 2.4 nm), shows H-alpha and H-beta lines with a complex shape superimposed on a relatively blue continuum. The Balmer lines consist of a broad compoment (FWHM about 6000 km/s) in emission, superimposed by a second component having a narrow-but-resolved emission profile (expansion velocity about 1000 km/s and emission peaks measured at 683.8 and 506.0 nm). From these peaks, a redshift of 0.0415 is derived for the parent galaxy. A comparison with a library of supernovae spectra via GELATO (Harutyuyan et al. 2008, A.Ap. 488, 383), gives a best fit with the type-IIn supernova 1995G (Pastorello et al. 2002, MNRAS 333, 27).
