Supernova 2012bo in NGC 4726 = PSN J12504523-1416085.

Abstract (from CDS):

M. R. Drout, D. Milisavljevic, A. Soderberg, and E. Berger, Harvard University, report on low-dispersion spectra (range 330-850 nm), taken on Mar. 29.4 UT with the 6.5-m MMT (+ Blue Channel), show PSN J12504523-1416085 = SN 2012bo to be a type-Ia supernova near maximum light. Comparison with a library of supernova spectra using the "Supernova Identification" tool (SNID; Blondin and Tonry 2007, Ap.J., 666, 1024) provides a good match with the normal type-Ia supernova 2003du at six days before maximum. Using the host- galaxy (NGC 4726) redshift of z = 0.025 (Jones et al. 2009, MNRAS 399, 683) the velocity of the Si II 635.5-nm feature is estimated to be approximately -11000 km/s.
