SUPERNOVA 2011gk IN UGC 1523
     L. Magill and R. Kotak, Queen's University, Belfast, report that an
optical spectrogram (range 350-900 nm) of PSN J02021902+1939396 = SN 2011gk
(cf. CBET 2845) was obtained at the Nordic Optical Telescope (+ ALFOSC) by M.
B. Nielsen on Sept. 29.03 UT.  The spectrum was cross-correlated with a
library of supernova spectra using the SNID software.  The best fit was with a
normal type-Ia supernova, similar to SN 2004eo at an epoch of 23 days (Mazzali
et al. 2008, MNRAS 386, 1897), in agreement with CBET 2845.  Fitting with SNID
yields a redshift of 0.045.  No Na I D lines are observed at the rest
wavelength of the Milky Way.  However, there is an Na I D line observed at
the rest wavelength of the host galaxy, UGC 1523, suggesting that there is
reddening due to the host galaxy, but no reddening due to the Milky Way.  The
spectral line is found at an uncorrected wavelength of 615.6 nm and was found
to have an equivalent width of 0.133 nm.
