SUPERNOVA 2009gh IN MCG +12-18-2
     P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf
of the CfA Supernova Group, reports that a spectrum (range 360-750 nm) of
2009gh (cf. CBET 1850), obtained on June 20 UT by M. Calkins with the F. L.
Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-IIP
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 2009gh best resembles that of the type-IIP
supernova 2004et at two weeks after maximum brightness.
