Abstract (from CDS):
---------------------------------------------------------------------------— SN 2009 UT R.A. (2000.0) Decl. Mag. Offset ---------------------------------------------------------------------------— 2009ji Sep. 23.14 15 54 52.48 +32 05 05.6 17.9 1".5 E, 2".7 N ---------------------------------------------------------------------------—
Nothing was visible at this position on a CSS image taken on Aug. 2.25 UT (limiting mag 20.9). Confirming spectroscopic observations (range 380-770 nm) of 2009ji were taken on Sept. 25.75 with the BTA 6-m telescope. Cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows this to be a type-Ia supernova, most similar to SN 2003du at 11 days past maximum light. The redshift is estimated to be z = 0.048.
