Confirming spectra (range 380-900 nm) were obtained using the SMARTS 1.5-m telescope on 2009 Mar. 27 and Apr. 20 UT and reveal Balmer lines (strong H-alpha, H-beta, H-gamma) and He I lines (587.6, 706.5 nm). H-beta exhibits a P-Cyg-like profile. No significant evolution is seen between the two spectra. The spectra closely resemble those of the slowly evolving type-IIn supernova 2007rt at 500 days past explosion (Trundle et al. 2009, http://lanl.arxiv.org/abs/0904.0119). Based on the redshift (z = 0.041) and the Palomar photometry, the peak absolute Gunn r magnitude was about -18.8.
