     Further to IAUC 8452, S. Park and W. Li report the LOSS
     discovery of an apparent supernova (mag 17.1) on an unfiltered KAIT
     image taken on Dec. 12.43 UT.  SN 2004gs is located at R.A. =
     8h38m23s.18, Decl. = +17o37'39".8 (equinox 2000.0), which is 9".8
     west and 12".7 south of the nucleus of MCG +03-22-20.  A KAIT image
     taken on Dec. 4.42 already showed a hint of the new object
     (limiting mag about 19.5), while an image taken on Nov. 24.45
     showed nothing at this position (limiting mag about 19.0).
