SUPERNOVA 2009fr IN NGC 597
      M. Stritzinger, Las Campanas Observatory; and G. Folatelli, Universidad
de Chile, on behalf of the Carnegie Supernova Project and the Millennium
Center for Supernova Science, report that they obtained an optical spectrogram
of supernova 2009fr (cf. CBET 1827) on Sept. 12.1 UT with the Gemini South
telescope (+ GMOS).  The spectrum reveals that this is an old type-IIP
supernova.  With the aid of the "Supernova Identification" code (SNID; Blondin
and Tonry 2007, Ap.J. 666, 1024), 2009fr is found to be most similiar to the
type-IIP supernova 1992H around 260 days past explosion.
