SUPERNOVA 2010eb IN NGC 488
     L. A. G. Monard, Pretoria, South Africa, reports his discovery of an
apparent supernova (magnitude 14.7) on an several unfiltered CCD images taken
on June 12.149 UT at the Bronberg Observatory; it was then confirmed on
pre-discovery images that he had taken on May 26.155, when 2010eb was at
magnitude 14.0.  The new object is located at R.A. = 1h21m37s.78, Decl. =
+5d17'39".9 (equinox 2000.0), which is 134" west and 135" north of the galaxy
core of the nearby type-Sb galaxy NGC 488.  Nothing is seen at this position
on Digitized Sky Survey images (limiting red mag 20.5), on the previous
image of this galaxy taken at the Bronberg Observatory on 2009 Nov. 26.759
(limiting mag 18.0), or on earlier images by Monard.
