SUPERNOVA 2009fs IN UGC 11205
     P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf
of the CfA Supernova Group, reports that a spectrum (range 360-750 nm) of
2009fs (cf. CBET 1829), obtained on June 4 UT by W. Brown with the F. L.
Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-IIn
supernova.  Cross-correlation with a library of supernova spectra using the
"Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666, 1024)
indicates that the spectrum of 2009fs best resembles that of the type-IIn
supernova 1998S at a phase of 13 days before maximum brightness.  The
redshift, as measured from emission lines in the host galaxy, is 0.053.
