SUPERNOVA 2010dr IN MCG +08-1-3
     T. Boles, Coddenham, England, reports the discovery of an apparent
supernova (mag 18.5) on unfiltered CCD images taken on June 3.086 and 4.057
UT with a 0.35-m reflector.  The new object is located at R.A. = 23h52m13s.04
+/- 0s.01, Decl. = +47o23'42".5 +/- 0".1 (equinox 2000.0), which is
approximately 16".4 east and 1".1 south of the center of MCG +08-1-3.  Nothing
is present at this position on Boles' images from 2009 Oct. 18 and Sept. 10
(limiting mag 19.5) or on Digitized Sky Survey plates from 1989 Sept. 28
(limiting red mag 20.5) and 1993 Aug. 21 (limiting blue mag 21.0).
