Xpress MX716 CCD camera).  The new object, which was confirmed at mag 16.5
on co-added images taken on Sept. 10.07 and 10.09, is located at R.A. =
6h07m59s.00, Decl. = +39o15'54".4 (equinox 2000.0), which is 12".5 east and
5".8 south of the center of the galaxy MCG +07-13-6 (= PGC 18452).  Nothing is
visible at this position on his co-added images taken on 2008 Oct. 6.96, Nov.
1.97, Dec. 23.79, and 2010 Feb. 7.77 (limiting mag 18.3).  An image of 2010hr
