A. S. Moskvitin, T. A. Fatkhullin, V. N. Komarova, V. V. Sokolov, and T. N. Sokolova, Special Astrophysical Observatory (SAO), Russian Academy of Sciences, report that a CCD spectrogram (range 380-790 nm; 1-nm resolution) was taken of 2011ej with the 6-m BTA telescope (+ Scorpio) on July 7 UT. The spectrum reveals strong H I and Fe II lines. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows matches with the spectrum of the type-II-P supernova 2004et at phase +6 days, redshifted to z = 0.042 ± 0.004. The authors report magnitude V = 18.91 ± 0.03 for 2011ej, obtained with the same instrument on July 7.988.
