POSSIBLE SUPERNOVA IN UGC 4543
     Grzegorz Duszanowicz, Akersberga, Sweden, reports his discovery of an
apparent supernova (mag 17.5) on an unfiltered CCD image (limiting mag 18.5)
taken on Sept. 30.13 UT with a 0.32-m f/3.1 reflector (+ Starlight Xpress
MX716 CCD camera).  The new object is located at R.A. = 8h43m21s.41, Decl. =
+45o44'18".0 (equinox 2000.0), which is 1".9 west and 9".6 north of the center
of UGC 4543 (= PGC 24493).  Nothing is visible at this position on a Digitized
Sky Survey image (limiting red mag 20-21).  Additional magnitudes for the
variable:  2009 Nov. 26.06, [18.5; 2010 Oct. 4.97, 17.3; 5.00, 17.3.  He has
