SUPERNOVA 2009T
     P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf
of the CfA Supernova Group, reports that a spectrum (range 320-850 nm) of
2009T (cf. CBET 1676), obtained on Feb. 2 UT by E. Falco with the F. L.
Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia
supernova.  Cross-correlation with a library of supernova spectra using the
"Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024) indicates that 2009T is 30-40 days past maximum brightness.
