Further to IAUC # 8622 , R. Quimby and P. Mondol report the discovery of a supernova in unfiltered CCD images taken on June 9.22 (at magnitude about 17.2), using the 0.45-m ROTSE-IIIb telescope at the McDonald Observatory. The supernova (coordinates RA 13:08:01.23 DEC +26:06:59.0 J2000.0) is 2.3" east and 13.1" south of the center of the apparent host galaxy (catalogued redshift of z = 0.035831 from Rines et al. 2001, ApJL 561, 41 via NED). The supernova was found by subtracting a co-addition of images taken between 2004 Dec. 15 and 2006 Jan. 10 (limiting magnitude about 19.3) from the 2006 June images.
The Nearby Supernova Factory reports that a spectrum (range 320-1000 nm) of this object, obtained June 10.4 UT with the Supernova Integral Field Spectrograph on the University of Hawaii 2.2-meter telescope, reveals it to be a Type IIn supernova, exhibiting narrow emission features from H-alpha throught H-delta, and also He I 587.6, 667.8, and 706.5 nm.
