2010CBET.2138....2K

I. K. W. Kleiser, J. M. Silverman, S. B. Cenko, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 350-1020 nm), obtained on Jan. 16 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that 2010N is a type-Ia supernova that SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) indicates is about 2 to 3 weeks past maximum. From narrow emission features, it is found that the recession velocity of 2010N's host galaxy is about 6400 km/s.
