2011CBET.2752....2S

J. M. Silverman and A. V. Filippenko, University of California, Berkeley, report that inspection of a CCD spectrum (range 340-1000 nm), obtained by J.-H. Woo, H.-J. Bae, D. Park, and D. Son (Seoul National University) on June 10 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that PSN J14243612+3516387 = SN 2011dt is a young type-II supernova with a relatively blue continuum. After removal of the host-galaxy recession velocity of 8300 km/s, determined from narrow emission lines, the absorption minimum of the H-alpha line (which is greatly dominated by the emission component) is found to be blueshifted by 7900 km/s.
