D. Balam, Dominion Astrophysical Observatory, National Research Council of Canada (NRCC); M. L. Graham, Las Cumbres Observatory Global Telescope, University of California at Santa Barbara; E. Y. Hsiao, Lawrence Berkeley Laboratory; and D. W. E. Green, Harvard University, report that a spectrogram (range 383-717 nm, resolution 0.3 nm) of PSN J18425421+5302415 = SN 2011eg, obtained on July 23.48 UT with the 1.82-m Plaskett Telescope of the NRCC, shows it to be a type-II-plateau supernova several days past maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2011eg is most similar to the type-II-plateau supernova 2004et at 4 days past maximum light. A second spectrogram taken on July 28.35 shows 2011eg to be a type-IIp supernova most similar to SN 1999em within several weeks of maximum light.
