2010CBET.2522....1M

D. Milisavljevic and R. Fesen, Dartmouth College, report that a low-dispersion spectrum (range 450-750 nm), taken on Oct. 31 UT with the 2.4-m Hiltner telescope (+ MKIII) at MDM Observatory following posting on the Central Bureau's unconfirmed-objects webpage, shows that 2010jc (cf. CBET 2521) is a type-IIP supernova just after maximum light. Comparison with a library of supernova spectra using the "Supernova Identification" tool (SNID; Blondin and Tonry 2007, Ap.J., 666, 1024) provides good matches with type-IIP events such as SN 2005cs at three days after maximum.
