Cenko, and A. V. Filippenko, University of California, report the LOSS discovery of an apparent supernova on unfiltered KAIT images: SN 2009 UT R.A. (2000.0) Decl. Mag. Offset 2009iz Sept. 19.52 2 42 15.41 +42 23 50.1 18.2 12".3 W, 14".5 N Additional KAIT magnitude for 2009iz in UGC 2175: Jan. 2.25 UT, [19.6; Sept. 7.45 UT, [18.2; 20.40 UT, 18.3. J. M. Silverman and A. V. Filippenko, University of California, Berkeley; and R. J. Foley, Center for Astrophysics, report that inspection of a CCD spectrogram (range 320-1020 nm), obtained on Sept. 22 UT with the Keck I 10-m telescope (+ LRIS), shows that the object is a type-Ib or type-Ic supernova; weak He I lines appear to be present, but should strengthen with time if the object is a normal type-Ib event. The redshift of the host galaxy, measured from narrow emission lines, is 0.014.
