2012CBET.2997....2M

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 J07211428-6205308 = SN 2011kb is a type-II supernova several months after explosion. SNID suggests for 2011kb a redshift of 0.010 (similar to the neighboring galaxy NGC 2369B) and gives good matches with a variety of type-II supernovae between 4 and 6 months after maximum brightness. Combining this information with the discovery date, it is possible to infer that the best reliable match is with the type-II-P supernova 2004et at 147 days after maximum light.
