Bufano, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova; and A. Pastorello, Belfast University, report that a spectrogram (range 380-780 nm, resolution 2.4 nm) of 2009E (cf. CBETs 1648 and 1734), obtained on Mar. 24.88 UT with the Copernico 1.82-m telescope (+ AFOSC), shows it to be an evolved type-II supernova, probably about 3 months after the explosion. The spectrum shows prominent lines of H, Ca II, Na I, Fe II, Ti II, Ba II, and Sc II with P-Cyg profiles. In particular, in analogy with SN 1987A, the Ba II features are unusually strong. Assuming a recession velocity of 1897 km/s (Theureau et al. 1998, A.Ap. Suppl. 130, 333; via NED) for the host galaxy, the "GELATO" spectrum-comparison code (Harutyunyan et al. 2008, A.Ap. 488, 383; available at https://gelato.tng.iac.es) provides good fits to spectra of type-II-plateau supernovae towards the end of the plateau phase. The expansion velocity deduced from the H-alpha absorption is about 5400 km/s.
