L. Tomasella, S. Benetti, E. Cappellaro, P. Ochner, A. Pastorello, M. Turatto, and S. Valenti, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that a spectrogram of PSN 11442941+0703463 = 2012bx, obtained on Apr. 24.99 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 340-820 nm; resolution 2.4 nm), indicates that this is a type-Ia supernova. Cross-correlation with a library of supernova spectra via the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2012bx is similar to SN 1995D (Sadakane et al. 1996, PASJ 48, 51) at 11 days after maximum at a redshift z = 0.049. The redshift is fully consistent with the redshift of the host galaxy, SDSS J114430.51+070337.6 (z = 0.0508, Sloan Digital Sky Survey Data Release 5, as obtained from website URL http://www.sdss.org/dr5/products/catalogs/index.html).
