| dc.description.abstract | Report the discovery of an apparent supernova in public images from the Mount Lemmon Survey: SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011ik Nov. 24.20 2 25 04.09 +22 12 51.9 17.9 7".1 W, 9".3 S The variable was designated PSN J02250409+2212519 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011ik based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2011ik: Nov. 26.292 UT, 18.7 (Joseph Brimacombe, Cairns, Australia; observed remotely using a 51-cm RCOS telescope + STL11K camera + luminance filter at the New Mexico Skies Observatory near Mayhill, New Mexico; position end figures 04s.19, 53".6; image posted at the following website URL: http://www.flickr.com/photos/43846774@N02/6411553661/); 27.350, 17.2 (R. A. Koff, Bennett, CO, USA; Meade 0.25-m f/10 reflector + unfiltered Apogee AP-47p camera; limiting magnitude 18.7; marginal detection in galaxy glow; position end figures 04s.06, 53".0; UCAC3 reference stars). 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 J02250409+2212519 = 2011ik was obtained on Nov. 26 UT by P. Berlind 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 2011ik is a type-Ia supernova more than two weeks after maximum light. A good fit is found to the template of the normal type-Ia supernova 2003cg at +24 days.... | |
