SUPERNOVAE 2013ft IN NGC 7732

Further to CBET 3606, K. L. Fuller, W. Zheng, W. Li, and A. V. Filippenko,
University of California at Berkeley; and S. B. Cenko, Goddard Space Flight
Center, report the LOSS discovery of an apparent supernova in NGC 7732 on
unfiltered KAIT images:

 SN       2013 UT        R.A. (2000.0) Decl.      Mag.      Offset
 2013ft   Sep. 13.29   23 41 35.20  + 3 43 30.5   18.6    20".4 E, 0".5 N

A finding chart for the new object was posted at the following website URL:
http://astro.berkeley.edu/~zwk/findingchart/PSN_J23413520+03433047.jpg.  The
variable was designated PSN J23413520+0343305 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2013ft based on the
spectroscopic confirmation reported below.  Additional approximate CCD
magnitudes for 2013ft:  Sept. 11.3 UT, [19.0 (KAIT); 14.2, 18.6 (KAIT);
