O'Connor, and A. Hirschauer, University of Notre Dame, report that a spectrum (range 380-780 nm) of 2006nr (cf. CBET 742) was obtained with the Kitt Peak 4-m Mayall telescope (+ R-C spectrograph) on Nov. 18.4 UT. The low-resolution spectrum shows broad emission features that are characteristic of a type-Ia supernova approximately three weeks past maximum light.
