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


Abstract (from CDS):

Koichi Itagaki, Yamagata, Japan reports his discovery of an apparent supernova (mag 16.4) on an unfiltered CCD image (limiting magnitude 19.5) taken on Mar. 27.709 UT with a 0.60-m f/5.7 reflector. The new object is located at R.A. = 12:50:45.23, Decl. = -14:16:08.5 (equinox 2000.0; UCAC3 reference stars), which is 12".4 west and 1".5 south of the nucleus of the presumed host galaxy, NGC 4726. Itagaki posted his discovery image at website URL The variable was designated PSN J12504523-1416085 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012bo based on the spectroscopic confirmation reported below. Additional magnitudes for 2012bo (unfiltered CCD unless noted otherwise): 1992 May 24, [19.3 (Digitized Sky Survey, red plate; via T. Yusa, Osaki, Japan); 2005 May 5.62, [19.0 (Itagaki); Mar. 28.280, 17.4 (Yusa; remotely using a 0.25-m f/3.4 hyperbolic astrograph + SBIG ST-8XE camera at the New Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures 45s.20, 08".1; offset 12".6 west, 1".0 south; UCAC-3 reference stars; limiting magnitude 19.5; image posted at the following website URL:; 28.285, 16.1 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera + luminance filter at the New Mexico Skies Observatory; position end figures 45s.21, 07".9; image posted at website URL; 28.515, 16.5 (T.
