SUPERNOVA 2011jz IN PGC 15984 = PSN J04464170-6228022
     L. A. G. Monard, Calitzdorp, Western Cape, South Africa, reports his
discovery of an apparent supernova (mag 18.3) on several unfiltered CCD images
taken on 2011 Nov. 25.015 UT.  The new object is located at R.A. =
4h46m41s.70, Decl. = -62d28'02".2 (equinox 2000.0), which is 12" west and 12"
south of the core of the Scd-type galaxy ESO 085-1 = PGC 15984.  Nothing is
visible at this position on Digitized Sky Survey images (limiting red mag
20.5).  The variable was designated PSN J04464170-6228022 when it was posted
at the Central Bureau's TOCP webpage and is here designated SN 2011jz based
on the spectroscopic confirmation reported below.  Additional CCD magnitudes
for 2011jz (unfiltered unless noted otherwise):  2011 Oct. 4.040, [19.0
(Monard); Nov. 26.014, 18.5 (Monard); 26.556, 17.7 (Joseph Brimacombe, Cairns,
Australia; 41-cm RCOS telescope + STL6K camera + infrared filter; range > 700
nm; position end figures 41s.83, 02".0; image posted at the following website

     N. Morrell, Las Campanas Observatory, on behalf of the Carnegie Supernova
Project, reports that optical spectroscopy (range 430-1000 nm), obtained on
2012 Jan. 16 UT with the 6.5-m Magellan I (Baade) telescope (+ IMACS), shows
that PSN J04464170-6228022 = SN 2011jz is a somewhat-evolved type-II supernova.
Comparison with a library of supernova spectra via the Supernova Identification
tool (SNID; Blondin and Tonry, 2007, Ap.J. 666, 1024) suggests that 2011jz is
most similar to the type-II-P supernova 2004dj at 36 days past maximum light.
