dc.description.abstractReport the discovery of an apparent supernova in public images from the Catalina Sky Survey (CSS). SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011jm Dec. 24.49 12 54 51.10 + 2 39 14.9 14.8 0".6 E, 0".2 N The variable was designated TCP J12545110+0239149 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011jm based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2011jm (unfiltered unless noted otherwise: June 24.18 UT, [19.0 (CSS); Dec. 27.489, 15.4 (J. Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera + luminance filter at the New Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures 51s.14, 15".1); 12.168, 15.6 (F. Luppi and L. Buzzi, Varese, Italy; 0.38-m f/6.8 reflector; position end figures 51s.11, 15".2; reference stars from CMC-14 catalogue; image posted at website URL http://www.astrogeo.va.it/pub/TOCP/TCP_N4809.jpg); 28.403, 15.5 (S. Baroni, L. Buzzi, P. Concari, S. Foglia, G. Galli, and M. Tombelli; remotely using a 0.18-m f/2.8 reflector at the Tzec Maun Observatory near Mayhill, NM, U.S.A.). Brimacombe's image is posted at the following website URL: http://www.flickr.com/photos/43846774@N02/6585388995/. R. J. Foley and W. Fong, Harvard-Smithsonian Center for Astrophysics, report that they have obtained a spectrogram (range 400-1000 nm) of TCP J12545110+0239149 = SN 2011jm on Dec. 27.3 UT with the Magellan Baade telescope (+ IMACS). The spectrum shows that 2011jm appears to be a type-Ic supernova 2-4 months after maximum light, but it is not fully nebular....
