Magill and R. Kotak, Queen's University, Belfast, report that an optical spectrogram (range 350-900 nm) of PSN J05014307-1523247 = SN 2011gl (cf. CBET 2846) was obtained at the Nordic Optical Telescope (+ ALFOSC) by M. B. Nielsen on Sept. 29.22 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 1981B at epochs of 23-24 days (Branch et al. 1983, A.J. 270, 123), in agreement with CBET 2846. Fitting with SNID yields a redshift of 0.038. NOTE: These 'Central Bureau Electronic Telegrams' are sometimes superseded by text appearing later in the printed IAU Circulars.
