SUPERNOVA 2010ia
     G. H. Marion, Harvard-Smithsonian Center for Astrophysics (CfA), on
behalf of the CfA Supernova Group; and T. Axelrod, Steward Observatory,
University of Arizona, report that a spectrum (range 560-1060 nm) of 2010ia
(cf. CBET 2463) was obtained on Sept. 20 UT by Axelrod, A. Saha (National
Optical Astronomical Observatory), and A. Vaz (Massachusetts Institute of
Technology) with the Kitt Peak National Observatory 4.0-m telescope using the
RCSpec 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 2010ia is a type-Ia supernova about two months
past maximum light.
