Supernova 2011gq = PSN J21422844-1606305.

MAGILL L., KOTAK R. and NIELSEN M.B.

Abstract (from CDS):

L. Magill and R. Kotak, Queen's University, Belfast, report that an optical spectrogram (range 350-900 nm) of PSN J21422844-1606305 = SN 2011gq was obtained at the Nordic Optical Telescope (+ ALFOSC) by M. B. Nielsen on Sept. 28.85 UT. After cross-correlated with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024), the best fit was with a normal type-Ia supernova and similar to SN 1998aq at an epoch of 66 days (Branch et al. 2003, A.J. 126, 1489). Fitting with SNID yields a redshift of 0.053.
