SUPERNOVA 2010it IN NGC 1417
     G. H. Marion, Harvard-Smithsonian Center for Astrophysics and University
of Texas; J. Vinko, University of Szeged; and J. C. Wheeler, University of
Texas, report that a spectrum (range 430-1000 nm) of 2010it (cf. CBET 2498)
was obtained by J. Caldwell on Oct. 15 UT with the 9.2-m Hobby-Eberly
Telescope (+ Marcario Low-Resolution Spectrograph).  Cross-correlation with a
library of supernova spectra using the "Supernova Identification" code (SNID;
Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2010it is a type-Ia
supernova a few days before maximum brightness.  The velocity of the Si II
635.5-nm feature is measured to be 10400 km/s.
