SUPERNOVA 2010ce
     M. Catelan, Pontificia Universidad Catolica de Chile; A. J. Drake, S. G.
Djorgovski, A. Mahabal, M. J. Graham, and R. Williams, California Institute
of Technology; J. L. Prieto, Carnegie Observatories; E. C. Beshore and S. M.
Larson, Lunar and Planetary Laboratory, University of Arizona; and E.
Christensen, Gemini Observatory, report that inspection of a CCD spectrogram
(range 370-920 nm), obtained on Apr. 21 UT with the SMARTS 1.5-m telescope
(+ RCSpec) at Cerro Tololo, shows that 2010ce (cf. CBET 2258) is a normal
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 2010ce is a week past maximum brightness and
is at a redshift of 0.06.
