SUPERNOVA 2004ci IN NGC 5980

     Further to IAUC 8349, M. Armstrong reports his discovery, on
     images taken on June 16.997 UT, of an apparent supernova (mag 17.5)
     located at R.A. = 15h41m29s.83, Decl. = +15o47'13".1 (equinox
     2000.0), which is 10".1 west and 2".3 south of the center of NGC
     5980.  Nothing was visible at this location on an image taken by
     Armstrong on 2003 Apr. 8.  Further to IAUC 8345 and 8350, S. Park
     and R. J. Foley also report LOSS observations of SN 2004ci via KAIT
     images taken on June 15.3 (mag about 17.7) and 17.3 (mag about
     17.4), giving position end figures 29s.71, 12".7.  A KAIT image
     taken on June 12.4 showed nothing at this position (limiting mag
     about 19.0).
