dc.description.abstractReport the Catalina Real-time Transient Survey's discovery of an apparent supernova in public images from the Catalina Sky Survey (CSS). SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011be Mar. 25.14 9 22 52.62 +21 59 15.7 17.7 6".2 W, 43".7 N Further unfiltered CCD magnitude estimates of 2011be: Mar. 11.23 UT, [19.7 (CSS); 26.17, 17.1 (remotely using a 0.5-m LB-1 telescope at Rodeo, NM, U.S.A.). 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 J09225262+2159157 = SN 2011be was obtained on Apr. 2 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 the object is a type-Ia supernova near maximum light. Using a redshift of z = 0.0348, measured from host-galaxy emission lines, the velocity of the Si II 635.5-nm feature is estimated to be approximately 10700 km/s....
