SUPERNOVA 2010hl IN MCG +10-24-122
     T. Boles, Coddenham, England, reports the discovery of an apparent
supernova (mag 17.5) on an unfiltered CCD image taken on Sept. 2.904 UT with a
0.35-m reflector.  The new object is located at R.A. = 17h16m33s.34 +/- 0s.01,
Decl. = +57o52'08".3 +/- 0".1 (equinox 2000.0), which is approximately 2".0
west and 0".4 south of the center of MCG +10-24-122.  Nothing is present at
this position on Boles's images from 2010 July 18 and May 10 (limiting mag
19.5) or on Digitized Sky Survey plates from 1993 Apr. 22 (limiting red mag
20.5) and 1991 Apr. 16 (limiting blue mag 21.0).  Boles also measured
magnitude V = 17.4 for 2010hl on Sept. 3.1754 using an image taken with a
0.61-m Cassegrain reflector at the Sierra Stars Observatory, Alpine County,
California (limiting mag 20.5).  He has posted images at the following
