SUPERNOVA 2006cj
     Further to IAUC 8622, R. Quimby, P. Mondol, and F. Castro,
University of Texas, report the discovery of an apparent supernova
in unfiltered CCD images taken on May 17.23 (at mag about 18.1),
18.24 (mag about 18.0), and 19.28 UT (poor conditions; mag about
17.7) with the 0.45-m ROTSE-IIIb telescope at the McDonald
Observatory.  SN 2006cj is located at R.A. = 12h59m24s.42, Decl. =
+28o20'51".7 (equinox 2000.0; estimated uncertainty 0".5 in each
coordinate), which is 4" east and 2" north of the center of the
apparent host galaxy (catalogued redshift of z = 0.068 from Cortese
et al. 2003, A.Ap. 401, 471; via NED).  SN 2006cj was found by
subtracting a co-addition of images taken between 2004 Dec. 15 and
2006 Jan. 10 (limiting mag about 19.3) from the 2006 May images.
