2010CBET.2209....1C

S. B. Cenko, B. E. Cobb, I. K. Kleiser, and A. V. Filippenko, University of California, Berkeley, report that inspection of a CCD spectrum (range 350-1000 nm), obtained on Mar. 15 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, reveals that 2010aj (CBET 2201) has a strong blue continuum, with broad absorption features that are indicative of a young type-II supernova. Cross-correlation with SNID (cf. Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that SN 2010aj is most similar to the type-II-P supernova 2006bp near maximum brightness.
