Abstract (from CDS):

E. Y. Hsiao, M. L. Graham, C. J. Pritchet, A. Parker, S. Sadavoy, and D. Balam, Department of Physics and Astronomy, University of Victoria, report that a spectrogram (range 390-703 nm, resolution 0.3 nm) of 2008gm (cf. CBET 1549), obtained on Oct. 23.17 UT with the 1.82-m Plaskett Telescope of the National Research Council of Canada, shows it to be a type-Ib/c supernova about 1 month past maximum light. Comparison with a library of supernova spectra using the "superfit" matching program of Howell et al. (2005, Ap.J. 634, 1190) indicates that 2008gm is most similar to the peculiar type-Ib/c supernova 1997ef with a weighted average epoch of 30 days past maximum light. The redshift derived from the fit is consistent with the published redshift of NGC 7530 (v = 3517 km/s; Theureau et al. 2005, A.Ap. 430, 373).
