dc.description.abstractReport the discovery of an apparent supernova in public unfiltered-CCD images from the Siding Spring Survey (SSS): SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011gl Sep. 23.71 5 01 43.07 -15 23 24.7 18.2 42".9 E, 29".7 N The variable was designated PSN J05014307-1523247 when it was posted on the Central Bureau's TOCP webpage and is here designated SN 2011gl based on the spectroscopic confirmation reported below. Additional unfiltered CCD magnitudes for 2011gl: Mar. 26.45 UT, [19.3 (SSS); Sept. 25.483, 17.7 (J. Brimacombe, Cairns, Australia; position end figures 43s.07, 25".3; image posted at website URL http://www.flickr.com/photos/43846774@N02/6183792395/. G. H. Marion, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that a spectrum (range 340-740 nm) of PSN J05014307-1523247 = 2011gl was obtained on Sept. 29 UT by Marion with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2011gl is a type-Ia supernova about two weeks after maximum light. The best-fit SNID template is to SN 2005am at +16 days and z = 0.043....
