SUPERNOVA 2011gh IN NGC 2405
L. Magill and R. Kotak, Queen's University, Belfast, report that optical
spectra (range 350-900 nm) were obtained at the Nordic Optical Telescope (+
ALFOSC) by M. B. Nielsen on Sept. 29.23 UT. The spectrum of PSN
J07321603+2554300 = SN 2011gh (cf. CBET 2841) is dominated by a narrow H_alpha
line of width 500 km/s. The redshift derived from this line agrees with the
redshift of NGC 2405 from NED (0.018890 +/- 0.000167; Marzke et al. 1996, A.J.
112, 1803). Given the lack of any other obvious features, and the lack of
flux at wavelengths shorter than 500 nm, Magill and Kotak concur with the
type-Ib/c classification of CBET 2841.
