| dc.description.abstract | Report the Catalina Real-time Transient Survey's discovery of an apparent supernova in unfiltered Catalina Sky Survey (CSS) images: SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011ag Feb. 25.15 3 12 26.55 +19 15 06.4 17.3 3".5 E, 20".0 N This object was designated PSN J03122655+1915064 on the Central Bureau's TOCP webpage, and is here designated SN 2011ag based on the spectroscopic report below. Further unfiltered CCD magnitudes for 2011ag: Feb. 4.11 UT, [20.4 (CSS); 27.089, 17.7 (R. A. Koff, Bennett, CO, U.S.A.; fourteen co-added 60-s images; position end figures 26s.55, 05".1). E. Y. Hsiao, N. Suzuki, and P. E. Nugent, Lawrence Berkeley National Laboratory, report that inspection of a CCD spectrum (range 350-980 nm), obtained on Feb. 27.25 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that 2011ag is a type-Ia supernova. The "superfit" software of Howell et al. (2005, Ap.J. 634, 1190) identified the spectrum as that of a type-Ia supernova around a week past maximum. The redshift matches that of the reported host galaxy (PGC 11943): z = 0.032. The spectrum closely resembles that of SN 1998bu at 10 days past maximum (Jha et al. 1999, Ap.J. Suppl. 125, 73).... | |
