2010CBET.2553....1F

G. Folatelli, IPMU, University of Tokyo; J. Anderson, Universidad de Chile; and G. Pignata, Universidad Andres Bello, on behalf of the Millennium Center for Supernova Science, report on an optical spectrogram (range 355-896 nm) of 2010jq (cf. CBET 2544) obtained on Nov. 17.29 UT with the SOAR telescope (+ Goodman HTS). The spectrum shows 2010jq to be an evolved type-Ia supernova, between two and three months after maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) provides good matches with spectra of SN 2003du at +72 and +84 days.
