Further to IAUC 8622, R. Quimby, University of Texas, reports the discovery of an apparent supernova in unfiltered CCD images taken with the 0.45-m ROTSE-IIIb telescope at the McDonald Observatory on Mar. 26.19 (at mag about 17.3) and Apr. 2.17 UT (mag about 17.2). The new object is located at R.A. = 12h22m19s.16, Decl. = +7o37'25".3 (equinox 2000.0; uncertainty ± 0".5), which is 1".1 east and 1".1 north of the center of the apparent host galaxy. The supernova was found by subtracting a co-addition of images taken between 2004 Dec. 15 and 2005 May 9 (limiting mag about 19.0). A spectrum (range 420-890 nm), obtained on Mar. 3.34 with the 9.2-m Hobby-Eberly Telescope (+ Marcario Low-Resolution Spectrograph) by S. C. Odewahn and F. Deglman, shows 2006bj to be a young type-II supernova. The spectrum consists of a blue continuum mostly devoid of features except for (most notably) a weak, broad absorption near 493 nm. Using narrow emission lines superimposed from the host galaxy, a redshift of z = 0.038 is calculated.
